Here are a few things you can do:
• Yoga and meditation. These mindfulness practices can help to lower your fatigue and stress. Any kind of exercise is also a good outlet for stress.
• Go for walks. Even if it seems to be the worst day of your life, going outside for a walk offers a great opportunity to change your mood.
• Imagery. Many people with cancer find imagery exercises can help manage pain and stress. To get started, close your eyes and think of a happy image in your mind. You can also think of an activity you like and let your mind linger. This may help you feel calmer.
