What you are feeling is 'normal' for us. I used to read a lot but found that being diagnosed and going through treatment was so unsettling that my mind could not concentrate on anything for long.
I had some DVD's of various TV shows and spent time watching them but even though they were only 30 minute episodes I would need to watch them more than once to actually take any of it in! I found doing Sudoku on my iPad was something I could do but again would loose concentration easily. I think this is perfectly understandable considering the serious nature of our diagnosis and treatment.
I found going for a walk helped to lift my mood. I think it is harder for young women like yourself to find a support group. I know in my area, the average age of the lovely ladies is close to 70. They are lovely but just do not have the same issues as younger women. I found that there were more younger people on here and I could find out how other people coped with things. There is almost always someone to listen and try to help you on here. People understand how you are feeling and don't mind if you share the hard times you are going through. Most of us have been there too.
You have probably noticed that for every down time there is usually a better time around the corner. If you find yourself feeling terrible for too long though, sometimes it helps to get some counseling type support. You can speak to counsellors on the phone through the cancer council or your GP maybe able to help. This is a really tough time and lots of us need a bit of help to get through it. xxx
