I would see if you could change the sleeping for reading or something that is slightly better/much less dangerous for you? I am reminded of author Cynthia Voigt's novel
The Runner,
http://www.amazon.com/The-Runner-Cyn.../dp/0590483803 where a guy just runs when he's feeling that messed up. I spent 10+ years reading and going to therapy before I finally was able to really get myself out of it. You cannot meet anyone new or get a job or make friends or anything unless you work on those things instead of sleeping/avoiding the pain.
