George,
I think I know all too well how you feel. It is easy to lose faith in the medical profession when we don't get the results expected. But everyone is different and it seems that everyone's cancer is different. What works for one does not always work for the other. At first I read these messages and gathered so much hope from others experiences. Over time I began to realize that what was true for others, isn't necessarily true in my father's case. Life isn't always fair, but while it lasts it can be beautiful.
And to look back upon the memories and smile is one of life's greatest gifts. I hope in time your anger will fade and be replaced with something more constructive. I'm sure your brother would not want you to live with such resentment associated with him. I hope you can find the peace and calm you so deserve after dealing with this bitch of a disease.
