Hey, ouch. I am glad that you are sticking to taking the anti-depressants. I seem to recall a major sleeping problem with them (sorry if I am wrong. I rarely remember people's nicks in subsequent visits.) I know what is to feel helpless too. As for friends, they tend to not know how to help or feel overwhelmed by it. So, they keep their distance. I hope you don't think that they don't care. They probably do. They just don't know how to help. You might could give them an idea of a small thing they can do to help without asking for too much.
I wish I could tell you how to get out. But, if I could do that I wouldn't have a compulsive need for my T. Try to give the anti-depressants and therapy time to help. They are both a rather gradual process.
