Navigating the New You: A Definitive Guide to Coping with CML Body Changes

A diagnosis of Chronic Myeloid Leukemia (CML) is a life-altering event, initiating a journey filled with medical appointments, treatment decisions, and often, a profound shift in how you experience your own body. While the primary focus of CML treatment is to manage the disease, the physical changes that can accompany this journey are often overlooked, yet they significantly impact daily life and emotional well-being. This comprehensive guide aims to equip you with the knowledge, strategies, and resilience needed to navigate these transformations, empowering you to not just cope, but to thrive amidst the new realities of living with CML.

Understanding the “why” behind these changes is the first step toward effective coping. CML treatments, primarily tyrosine kinase inhibitors (TKIs), are remarkably effective at targeting the abnormal cells responsible for the disease. However, these powerful medications can also affect healthy cells and processes, leading to a range of side effects that manifest as body changes. Furthermore, the disease itself, even before treatment, can contribute to alterations in your physical state. This guide will delve into these changes with a compassionate yet practical approach, offering actionable advice and real-world examples to help you reclaim a sense of control and comfort in your own skin.

The Shifting Landscape: Understanding Common CML-Related Body Changes

The body changes experienced with CML can be diverse, ranging from subtle alterations to more noticeable transformations. It’s crucial to remember that not everyone will experience all of these, and the intensity can vary greatly. Open communication with your healthcare team is paramount to understanding your specific side effects and how best to manage them.

Weight Fluctuations: The Unpredictable Scale

One of the most frequently reported body changes in individuals with CML is weight fluctuation. This can manifest as either weight gain or weight loss, and the reasons behind it are multifaceted.

Weight Gain: Many CML patients on TKI therapy experience weight gain. This isn’t simply about consuming more calories; it’s often a complex interplay of factors:

  • Fluid Retention: TKIs, especially certain types, can lead to fluid retention, causing bloating and an increase in scale weight that isn’t true fat gain. This might manifest as swollen ankles, puffy hands, or a general feeling of fullness.
    • Actionable Strategy:
      • Monitor Sodium Intake: While a low-sodium diet might seem counterintuitive for fluid retention, excessive sodium can exacerbate it. Focus on fresh, whole foods and limit processed items. Instead of heavily salted snacks, opt for fruits, vegetables, and unsalted nuts. For example, instead of potato chips, reach for an apple or a handful of unsalted almonds.

      • Stay Hydrated: Paradoxically, drinking enough water can help your body regulate fluid balance. Dehydration can sometimes trick your body into holding onto water. Carry a reusable water bottle and aim to sip throughout the day.

      • Regular, Gentle Movement: Even light activity like walking can help improve circulation and reduce fluid accumulation. Instead of sitting for prolonged periods, get up and move around for 5-10 minutes every hour.

      • Elevate Legs: If fluid retention is primarily in your lower extremities, elevate your legs when resting. Prop your feet up on pillows while watching TV or lying in bed.

      • Compressive Garments: Your doctor might recommend compression stockings if fluid retention in your legs is significant. These can help to reduce swelling and discomfort.

  • Metabolic Changes: Some TKIs can affect metabolism, making it harder for your body to process food efficiently and leading to increased fat storage.

    • Actionable Strategy:
      • Balanced Nutrition: Focus on a diet rich in lean proteins, complex carbohydrates, and healthy fats. This provides sustained energy and supports a healthy metabolism. Instead of a sugary breakfast cereal, choose oatmeal with berries and nuts.

      • Portion Control: Even healthy foods can contribute to weight gain if consumed in excess. Be mindful of portion sizes, using smaller plates or measuring cups to guide you. For instance, a serving of pasta is typically half a cup cooked.

      • Mindful Eating: Pay attention to your hunger and fullness cues. Eat slowly, savoring your food, and stop when you feel satisfied, not overly full. Avoid eating while distracted by screens.

  • Reduced Activity Levels: Fatigue, a common CML side effect, can lead to decreased physical activity, burning fewer calories and contributing to weight gain.

    • Actionable Strategy:
      • Incorporate Gentle Exercise: Even short bursts of activity can make a difference. Aim for 10-15 minutes of light walking a few times a day if a longer workout feels overwhelming. Try walking around your block or doing light stretching exercises at home.

      • Listen to Your Body: Don’t push yourself too hard on days you feel exceptionally fatigued. Rest is crucial, but try to remain as active as comfortable on good days.

Weight Loss: Less commonly, some individuals with CML may experience unintended weight loss. This can be due to:

  • Nausea and Appetite Changes: Certain TKIs can cause nausea, leading to a reduced appetite and difficulty consuming enough calories.
    • Actionable Strategy:
      • Small, Frequent Meals: Instead of three large meals, try eating 5-6 smaller meals or snacks throughout the day. This can be less overwhelming for your stomach. For example, instead of a large dinner, have a smaller portion of chicken and vegetables, followed by a piece of fruit later.

      • Bland Foods: Opt for bland, easy-to-digest foods when nausea is present, such as toast, crackers, rice, and plain chicken. Avoid strong-smelling or greasy foods.

      • Nutrient-Dense Snacks: Choose calorie-dense, nutritious snacks like avocados, nuts, nut butters, and full-fat dairy (if tolerated).

      • Liquid Nutrition: If solid food is difficult, consider nutrient-rich smoothies, protein shakes, or nutritional supplements recommended by your doctor or a dietitian. Blend fruit, yogurt, and a scoop of protein powder for a quick, nutritious meal.

      • Ginger: Ginger in various forms (ginger ale, ginger tea, crystallized ginger) can sometimes help alleviate nausea.

  • Increased Metabolism from Disease Activity: In some cases, the disease itself, particularly if it’s not well-controlled, can lead to an increased metabolic rate and unintentional weight loss.

    • Actionable Strategy: This is primarily managed through effective CML treatment. However, ensure you are consuming sufficient calories and nutrients to support your body.

Skin and Hair Changes: The Visible Impact

The skin and hair, being rapidly regenerating tissues, can be particularly susceptible to the effects of CML treatments.

Skin Changes:

  • Dryness and Itchiness: TKIs can disrupt the skin’s natural barrier, leading to dryness, flakiness, and persistent itching (pruritus).
    • Actionable Strategy:
      • Moisturize Regularly: Apply a thick, emollient moisturizer immediately after showering or bathing to lock in moisture. Look for fragrance-free, hypoallergenic options. For example, use a cream specifically designed for sensitive or eczema-prone skin.

      • Lukewarm Showers: Hot water strips natural oils from the skin. Opt for lukewarm showers and keep them short.

      • Gentle Cleansers: Avoid harsh soaps and fragranced body washes. Use a gentle, soap-free cleanser.

      • Humidifier: In dry environments, a humidifier can add moisture to the air, preventing skin dehydration. Place one in your bedroom.

      • Avoid Scratching: While tempting, scratching can worsen itching and lead to skin damage and infection. Instead, try applying a cool compress or a topical anti-itch cream (consult your doctor first).

      • Loose, Breathable Clothing: Wear soft, loose-fitting clothing made from natural fibers like cotton to prevent irritation.

  • Rashes and Photosensitivity: Some TKIs can cause various rashes, from mild redness to more significant skin eruptions. Increased sensitivity to the sun (photosensitivity) is also common.

    • Actionable Strategy:
      • Sun Protection: Be vigilant about sun protection. Wear broad-brimmed hats, sunglasses, and long-sleeved clothing when outdoors. Apply a broad-spectrum sunscreen with an SPF of 30 or higher liberally and reapply every two hours, especially after sweating or swimming. Even on cloudy days, UV rays can penetrate.

      • Avoid Peak Sun Hours: Limit outdoor activities during the sun’s peak hours (typically 10 AM to 4 PM).

      • Topical Treatments: Your doctor may prescribe topical corticosteroids or other creams to manage rashes. Do not self-treat.

  • Nail Changes: Nails can become brittle, discolored, or develop ridges.

    • Actionable Strategy:
      • Keep Nails Short: Trim nails regularly to prevent breakage and snags.

      • Moisturize Nails and Cuticles: Apply hand cream or cuticle oil to keep nails and cuticles hydrated.

      • Avoid Harsh Chemicals: Wear gloves when doing household chores or gardening.

      • Limit Nail Polish: Give your nails a break from polish to allow them to breathe.

Hair Changes:

  • Thinning or Loss: While not as dramatic as chemotherapy-induced hair loss, some TKIs can cause hair thinning or changes in hair texture.
    • Actionable Strategy:
      • Gentle Hair Care: Use a mild, sulfate-free shampoo and conditioner. Avoid harsh chemical treatments like perms or dyes.

      • Minimize Heat Styling: Limit the use of blow dryers, curling irons, and straighteners, as heat can further damage fragile hair. Air dry your hair whenever possible.

      • Soft Brushes: Use a wide-toothed comb or a soft-bristled brush to minimize breakage.

      • Nutrient-Rich Diet: Ensure your diet supports healthy hair growth with adequate protein, vitamins, and minerals.

      • Scalp Massage: Gentle scalp massage can stimulate blood flow to the hair follicles.

  • Changes in Hair Texture/Color: Hair may become more brittle, curly, or even change color in some individuals.

    • Actionable Strategy: Embrace the change! If your hair texture has shifted, explore new hairstyles that work with your new hair. If color changes occur, consult with your stylist about options that are gentle on your hair and scalp.

Muscle and Joint Pain: The Ache of Adaptation

Musculoskeletal pain, including muscle aches (myalgia) and joint pain (arthralgia), is a common complaint among CML patients on TKI therapy. This can significantly impact mobility and quality of life.

  • Actionable Strategy:
    • Regular, Gentle Exercise: While it may seem counterintuitive, regular, low-impact exercise can help alleviate pain and stiffness. Activities like walking, swimming, cycling, or tai chi can improve flexibility and strengthen supporting muscles. Start with short durations and gradually increase as tolerated. For example, begin with a 15-minute walk and aim to increase to 30 minutes over a few weeks.

    • Stretching: Incorporate gentle stretching exercises into your daily routine to improve flexibility and reduce muscle tension. Focus on major muscle groups.

    • Heat and Cold Therapy: Apply heat packs to sore muscles and joints to relax them, or use cold packs to reduce inflammation and numb pain. Experiment to see what works best for you. For a sore knee, try a warm compress before activity and an ice pack after.

    • Over-the-Counter Pain Relievers: Discuss with your doctor if over-the-counter pain relievers like acetaminophen or ibuprofen are safe and appropriate for you. Do not self-medicate without medical advice, as some medications can interact with TKIs.

    • Physical Therapy: A physical therapist can provide tailored exercises and techniques to strengthen muscles, improve range of motion, and manage pain. They can also teach you proper body mechanics to prevent further strain.

    • Massage Therapy: Gentle massage can help relax tense muscles and improve circulation.

    • Good Posture: Be mindful of your posture throughout the day, whether sitting, standing, or lifting. Good posture can reduce strain on your joints and muscles.

    • Ergonomic Adjustments: Ensure your workspace and home environment are ergonomically friendly. Use supportive chairs, adjust monitor height, and ensure comfortable sleeping positions.

Fatigue: The Invisible Burden

Fatigue in CML is more than just feeling tired; it’s a profound, persistent exhaustion that isn’t relieved by rest and significantly impacts daily functioning. It can be a direct side effect of treatment, a symptom of the disease itself, or a result of anemia.

  • Actionable Strategy:
    • Prioritize Rest: Acknowledge that you need more rest than before. Schedule naps if needed, but keep them short (20-30 minutes) to avoid interfering with nighttime sleep.

    • Pacing Activities: Break down tasks into smaller, manageable chunks. Alternate between active and rest periods. For example, instead of cleaning the entire house at once, clean one room, then rest, then tackle another.

    • Energy Conservation Techniques: Learn to delegate tasks, simplify routines, and avoid unnecessary energy expenditure. If you have stairs, try to consolidate trips up and down.

    • Regular, Gentle Exercise: Paradoxically, light to moderate exercise can improve energy levels in the long run. Even a short walk outdoors can boost mood and reduce fatigue.

    • Balanced Nutrition and Hydration: Ensure you’re fueling your body with nutrient-dense foods and staying well-hydrated. Dehydration can exacerbate fatigue.

    • Good Sleep Hygiene: Establish a consistent sleep schedule, create a relaxing bedtime routine, and ensure your bedroom is dark, quiet, and cool. Avoid caffeine and screens before bed.

    • Manage Stress: Stress can deplete energy reserves. Practice relaxation techniques like deep breathing, meditation, or gentle yoga.

    • Open Communication with Your Doctor: Discuss your fatigue levels with your healthcare team. They can rule out other causes, such as anemia, and suggest strategies or adjustments to your treatment plan if appropriate.

Oral Health Changes: Beyond the Smile

CML and its treatments can impact oral health, leading to discomfort and potential complications.

  • Actionable Strategy:
    • Maintain Excellent Oral Hygiene: Brush your teeth at least twice a day with a soft-bristled toothbrush and fluoride toothpaste. Floss daily.

    • Regular Dental Check-ups: Schedule regular dental appointments and inform your dentist about your CML diagnosis and treatment. They may recommend more frequent cleanings or specialized care.

    • Manage Dry Mouth (Xerostomia): If you experience dry mouth, sip water frequently, chew sugar-free gum, or use saliva substitutes. Avoid sugary or acidic foods and drinks.

    • Address Mouth Sores (Mucositis): If mouth sores develop, use a soft toothbrush and rinse your mouth with a mild, alcohol-free mouthwash or a saline solution. Avoid spicy, acidic, or rough foods. Your doctor may prescribe specific mouth rinses for relief.

    • Stay Hydrated: Adequate hydration supports saliva production and overall oral health.

Sexual Health and Intimacy: Reclaiming Connection

CML and its treatments can impact sexual health and intimacy, affecting libido, function, and body image. This is a sensitive but crucial aspect of overall well-being.

  • Actionable Strategy:
    • Open Communication with Partner: Talk openly and honestly with your partner about your feelings, physical changes, and any challenges you’re facing. This can foster understanding and strengthen your bond.

    • Communicate with Healthcare Team: Don’t hesitate to discuss sexual health concerns with your doctor or a specialist. They can offer solutions, refer you to specialists (e.g., sex therapist, urologist, gynecologist), or adjust medications if appropriate.

    • Explore Non-Penetrative Intimacy: Intimacy extends beyond penetrative sex. Explore other forms of physical closeness, such as cuddling, kissing, massage, and sensual touch.

    • Address Fatigue: Fatigue can significantly impact libido. Address fatigue using the strategies mentioned earlier.

    • Manage Body Image Concerns: If body changes are affecting your self-esteem and desire for intimacy, focus on self-compassion. Remind yourself that your body is fighting a battle, and its changes are a testament to your strength. Focus on what your body can do, not what it can’t.

    • Schedule Intimacy: In busy lives, and especially when dealing with health challenges, scheduling time for intimacy can be helpful. It removes pressure and ensures dedicated moments for connection.

    • Lubrication: If vaginal dryness is an issue, over-the-counter lubricants can significantly improve comfort during sexual activity.

Beyond the Physical: The Emotional and Psychological Impact

Coping with physical body changes from CML is not just about managing symptoms; it’s deeply intertwined with your emotional and psychological well-being. These changes can trigger a range of feelings, including frustration, sadness, anger, anxiety, and a sense of loss of your former self.

Body Image and Self-Esteem: Redefining Beauty

The alterations in your appearance due to CML can profoundly affect your body image and self-esteem. You might feel disconnected from your body, or that it no longer reflects who you are.

  • Actionable Strategy:
    • Practice Self-Compassion: Treat yourself with the same kindness and understanding you would offer a friend facing similar challenges. Acknowledge that your body is doing its best under difficult circumstances.

    • Focus on Strengths and Abilities: Shift your focus from perceived imperfections to what your body can do. Celebrate its resilience and the fact that it’s fighting a serious illness.

    • Engage in Self-Care Rituals: Indulge in activities that make you feel good about yourself, regardless of appearance. This could be a relaxing bath, listening to your favorite music, or spending time in nature.

    • Dress for Comfort and Confidence: Choose clothing that makes you feel comfortable and confident. This might mean adapting your wardrobe to accommodate new body shapes or skin sensitivities.

    • Limit Social Comparison: Avoid comparing your body to others, especially images in media that are often unrealistic.

    • Seek Professional Support: If body image issues are significantly impacting your mental health, consider speaking with a therapist or counselor specializing in chronic illness. They can help you process these feelings and develop healthier coping mechanisms.

Depression and Anxiety: Navigating the Emotional Storm

The cumulative effect of physical changes, coupled with the ongoing stress of a CML diagnosis, can increase the risk of depression and anxiety.

  • Actionable Strategy:
    • Acknowledge Your Feelings: It’s okay to feel sad, angry, or anxious. Suppressing these emotions can be detrimental.

    • Build a Strong Support System: Lean on friends, family, or support groups. Sharing your experiences with others who understand can be incredibly validating.

    • Practice Mindfulness and Meditation: These techniques can help you stay grounded in the present moment and manage overwhelming thoughts and emotions. There are many guided meditations available online.

    • Engage in Hobbies and Interests: Continue to pursue activities you enjoy, even if you need to adapt them. Hobbies provide a sense of purpose and distraction from worries.

    • Regular Physical Activity (as tolerated): Exercise is a powerful mood booster and can reduce symptoms of anxiety and depression.

    • Prioritize Sleep: Good sleep is fundamental for mental well-being. Address any sleep disturbances.

    • Limit News Exposure: While staying informed is important, excessive exposure to negative news can exacerbate anxiety.

    • Professional Help: If feelings of sadness or anxiety are persistent, overwhelming, or interfering with your daily life, seek professional help from a psychiatrist or therapist. They can offer therapy, medication, or a combination of approaches.

Practical Strategies for Daily Living

Beyond specific symptom management, adopting broader strategies for daily living can significantly improve your ability to cope with CML body changes.

Adapting Your Wardrobe: Comfort Meets Style

Your body shape might change, and your skin might become more sensitive. Adapting your wardrobe can greatly enhance comfort and confidence.

  • Actionable Strategy:
    • Prioritize Comfort: Choose soft, breathable fabrics like cotton, linen, and bamboo. Avoid restrictive clothing or irritating textures.

    • Layering: Layers allow you to adjust to temperature fluctuations and hide areas you might feel self-conscious about.

    • Flexible Waistbands: Opt for clothing with elasticated waistbands or adjustable ties if you experience bloating or weight fluctuations.

    • Embrace Loose Fits: Loose-fitting clothing can be more comfortable for sensitive skin and accommodate changes in body shape.

    • Invest in Good Undergarments: Supportive and comfortable bras and underwear can make a significant difference in how you feel.

    • Seek Expert Advice: If you’re struggling to find suitable clothing, consider consulting a personal stylist who specializes in adaptive clothing or has experience working with individuals with health conditions.

Nutrition and Hydration: Fueling Your Resilience

A well-balanced diet and adequate hydration are fundamental for managing CML symptoms and supporting your body through treatment.

  • Actionable Strategy:
    • Consult a Registered Dietitian: A dietitian specializing in oncology can provide personalized dietary advice tailored to your specific needs, side effects, and treatment plan. They can help with weight management, nausea, and ensuring adequate nutrient intake.

    • Focus on Whole Foods: Prioritize fruits, vegetables, lean proteins, whole grains, and healthy fats. These provide essential vitamins, minerals, and antioxidants.

    • Stay Hydrated: Drink plenty of water throughout the day. Water helps with digestion, nutrient absorption, and flushing out toxins. Carry a water bottle as a reminder.

    • Manage Appetite Changes: Implement strategies for nausea or poor appetite discussed earlier (small, frequent meals, bland foods).

    • Address Specific Deficiencies: Your doctor may recommend supplements if blood tests reveal deficiencies in certain vitamins or minerals. Do not self-supplement without medical advice.

    • Food Safety: Due to potential immunosuppression, practice strict food safety. Wash produce thoroughly, cook meats to proper temperatures, and avoid raw or undercooked foods.

Movement and Exercise: Reclaiming Your Body’s Strength

While fatigue and pain can make exercise challenging, incorporating gentle movement into your routine is crucial for physical and mental well-being.

  • Actionable Strategy:
    • Start Slow and Listen to Your Body: Begin with short durations of low-impact activities and gradually increase as your stamina improves. Don’t push through pain.

    • Variety is Key: Explore different forms of exercise to keep things interesting and work different muscle groups. This could include walking, swimming, gentle yoga, tai chi, or seated exercises.

    • Incorporate Strength Training: Even light resistance training using body weight or resistance bands can help maintain muscle mass, which can be lost during illness and treatment.

    • Work with a Physical Therapist or Exercise Physiologist: They can design a safe and effective exercise program tailored to your physical limitations and goals.

    • Schedule Exercise: Treat exercise like an important appointment and block out time for it in your day.

    • Exercise with a Buddy: Having a friend or family member join you can provide motivation and accountability.

    • Focus on Function: Rather than striving for peak performance, focus on how exercise helps you perform daily activities more easily.

Communication with Your Healthcare Team: Your Most Powerful Tool

Your healthcare team is your strongest ally in navigating CML body changes. Open and honest communication is vital.

  • Actionable Strategy:
    • Be Specific About Symptoms: Instead of saying “I feel tired,” describe your fatigue’s intensity, when it occurs, and how it impacts your daily life. “My fatigue is a 7/10 on most days, making it difficult to get out of bed before noon and I can only walk for 10 minutes before I need to rest.”

    • Keep a Symptom Journal: Track your symptoms, their severity, what makes them better or worse, and how they affect your daily activities. This provides valuable information for your doctor.

    • Ask Questions: Don’t hesitate to ask questions about your symptoms, treatment, and potential side effects. Write them down before your appointment.

    • Discuss Side Effect Management: Inquire about specific strategies or medications to manage particular side effects.

    • Advocate for Yourself: You are the expert on your own body. If you feel a side effect is unbearable or not being adequately addressed, speak up.

    • Bring a Loved One: Having a trusted friend or family member with you at appointments can help you remember information and advocate on your behalf.

    • Explore Patient Support Programs: Many pharmaceutical companies and patient organizations offer support programs, resources, and educational materials related to CML and its management.

Cultivating Resilience: A Mindset for Living Well

Coping with CML body changes is not a one-time event; it’s an ongoing process that requires resilience, adaptability, and a proactive approach.

Embrace Adaptability: The Power of Flexibility

Life with CML demands flexibility. Things won’t always go as planned, and you’ll need to adapt to new realities.

  • Actionable Strategy:
    • Accept What You Can’t Control: Focus your energy on what you can control (your attitude, self-care, communication with your team) rather than dwelling on what you can’t.

    • Be Open to New Approaches: If a coping strategy isn’t working, be willing to try something different.

    • Set Realistic Expectations: Understand that there will be good days and bad days. Don’t pressure yourself to be “normal” or perform at pre-diagnosis levels all the time.

    • Find Your “New Normal”: This isn’t about giving up; it’s about redefining what a fulfilling life looks like for you with CML.

Seek and Offer Support: The Strength in Connection

You don’t have to face CML alone. Connecting with others is a powerful coping mechanism.

  • Actionable Strategy:
    • Join Support Groups: Online or in-person support groups provide a safe space to share experiences, gain insights, and feel understood by others facing similar challenges.

    • Educate Loved Ones: Help your family and friends understand what you’re going through, both physically and emotionally. This allows them to offer more effective support.

    • Don’t Isolate Yourself: Even when you feel tired or down, try to maintain social connections. A quick phone call or virtual chat can make a difference.

    • Consider Peer Mentoring: Connecting with someone who has lived with CML for a longer period can offer invaluable practical advice and emotional support.

Celebrate Small Victories: Acknowledging Progress

The journey with CML is long, and it’s easy to get caught up in the challenges. Make a conscious effort to acknowledge and celebrate small victories.

  • Actionable Strategy:
    • Keep a Gratitude Journal: Regularly write down things you are grateful for, no matter how small. This shifts your focus to the positive aspects of your life.

    • Acknowledge Your Efforts: Pat yourself on the back for managing symptoms, completing a task despite fatigue, or simply getting through a difficult day.

    • Reward Yourself: When you achieve a goal or overcome a challenge, treat yourself to something enjoyable, whether it’s a new book, a relaxing bath, or a favorite meal.

Conclusion: Embracing Your Journey with Confidence

Living with CML and its accompanying body changes is an ongoing process of adaptation, learning, and self-discovery. It demands resilience, informed decision-making, and a compassionate approach to yourself. By understanding the underlying causes of these changes, proactively implementing actionable strategies for physical and emotional well-being, and maintaining open communication with your healthcare team, you can navigate this journey with greater confidence and comfort.

Remember, your body is incredibly strong, fighting a battle every day. Treat it with kindness, listen to its signals, and empower yourself with knowledge. While CML may alter your physical landscape, it does not define your identity or limit your capacity for a rich, meaningful life. By embracing these changes and actively managing their impact, you can continue to live fully, proving that adaptation is not just about coping, but about thriving.
