It's funny - though it has only happened to me a few of times (an luckily has not developed into a continuing problem) this has happened to me. 0 use of alcohol, then I get drunk when I'm really upset. I think it's easier to get drunk when you're upset too, so it does happen.

It's kind of the nature of this beast to be "extreme" - I mean, hurting yourself at all is SO CRAZY sounding if you haven't gone through it yourself

Glad you have a therapist - have you brought this up? What did they say? With my first one she would just say "don't do it anymore" and look at me really sternly (... didn't like that one and it DIDN'T WORK). In fact it made it worse because I felt doubly guilty for doing it in the first place and would do it more. But my next therapist really worked with me on the WHY and by that point I had developed some really good coping mechanisms (sometimes using a rubber band would help me too btw - it provides sudden sharpish pain which can sometimes hold off the urge, sometimes it doesn't work at all but wortha try you know? I heard ice also works for some people). And of course if you can tell you're heading in that direction get out and with people but it's rarely that simple in my experience anyways.

hope you feel better, take care!
