I'm sorry things are so tough for you at the moment.
If I have learned anything from my 25 odd years of drinking (during which I around moved a lot) it's that it didn't matter where I lived it was me that was the problem. I used to think that if I only lived somewhere where this happened or didn't happen or had more of this and less of that, then I'd be happy and wouldn't need to drink. But at the end of the day if you aren't happy with yourself nothing gets better.
I'm not saying don't travel it could be just what you need, but I wouldn't expect some Hollywood Eat, Pray, Love experience and everything is magically fixed when you come home.
