Not sure if this will help you... I have to read it sometimes to remind myself to stop feeling so angry or sad about things.. because I have a lot of why me moments.. see below: took most of it from a book I read....

If I let cancer make me bitter or angry, then I would of spent the last days of my life in sorrow and isolation; making a living hell for my loved ones, and be remembered if at all, a bitter old woman who let cancer defeat her.

I would receive their temporary show of sympathy, but in the end they would only have contempt for me and how I left them;

On the other hand:

If I were positive and hopeful, it wouldn't change the day of my death a bit, but, it would mean that I would spend the last days of my life breathing deeply, clearly, contented and blissful, and in love with my family and everyone I met...
I would die a happy woman and be remembered as that brave soul who faced a terrible death with courage, fortitude and aplomb.
I would be cherished by those who knew me.

Why waste months of my life wailing about an end that wasn't even near?
