how to deal with the fact that disease ruined your life?

This horrible disease ruined my life. Before the disease I was intelectually bright and I wanted to work at a think tank. But this monstrous disease ruined my life. I am stuck with my abusers and the only thing that I can do now is to get a simple job like janitors and the like which I don't want to work until I die. I had ambition and wanted to change my life for the better, but now it seems like I will be stuck with abusers in poverty.
