I am celebrating two years in remission now (stage 4 lymphoma). One of the greatest things a nurse told me was when you are tired get up and take a walk, when you are exhausted take a quick nap. No matter what don't stop moving! I saw so many people curl up into a ball and give up. Don't give it that chance! Keep moving, the motion keeps your mind and spirit going. My friend Rob Walker said it perfectly. Your faith will support you when your body cant. There will be days like that.
