I can't really give you much advice, because I'm just getting out of that period (now over 5 years) myself. But I do have one piece of advice: never let yourself, or anyone else, define you by your worst moments in life. Instead, define yourself by how you've learned from them and how that reflects in your current actions. Unlike most of the stuff you'll need to do to recover, this can be done instantly.

Also, to people who suggested moving somewhere else: while I do agree that it can provide a bit of a spark, that's all it'll do. You won't become a different person just by changing places. You need to act on it. I made the mistake of assuming that moving would change more than it did until it was too late.
