How bad can this get?

Well since I already only feel about 40% conscious and I'm feeling weak and sick pretty much 24/7 why won't this eventually kill me? It just keeps getting worse and worse. Recently my psychiatrist upped my Prozac so it's possible that that's making it a bit worse. I usually only have DR but lately I've been getting bouts of DP which to me is so much scarier, and when they happen at once it's like you don't even exist. Am I ever just going to keel over from this? Has anybody passed out?
