I think it is difficult to find peace while undergoing Chemo. The drugs affect your mood so it is a bumpy ride. Do you have times where you feel ok? I found it helped me to exercise as much as possible. The more I did the better I felt. It has the added bonus of being a proven way of reducing the risk of recurrence, so that is something you can do to help yourself.
I also found it helped to have little rewards for getting through each chemo, whatever helps you to feel good for a liitle while.
Have you read Mich's blog 'What helps you when you are down or stressed?' This is full of ideas from ladies who are dealing with BC. You do get through everything and feel better again. I find I only have down 'moments' now, not down hours or days. Once the effects of chemo are out of the body it does get easier, I think. Meanwhile I just keep focused on helping myself by exercising (6 km walk, 1km swim). I now look healthy again and this helps me to feel positive about the future. Take care. Keep in touch. Deanne xxx
