I called the National Suicide Prevention Hotline or some such. They weren't very helpful, to be honest, but it was a really good distraction - it's hard to cut when you have to hold a slippery phone and respond to questions at the same time. Thanks for the tip, bluechick At this point I think I'll be okay for another night, and I've learned that walking in combination with loud music tends to help (assuming I'm not getting my toes frozen off by all this ridiculous winter weather >.<).
Also, I know that some people on here think I am an attention seeker or that I am spreading "cutting porn". Please don't say things like that. I am a 15 year old girl who is struggling just like all of you, who is sometimes ambivalent about giving up the best coping skill she's ever found, who has trust issues and who finds it really difficult to surrender control to other people, i.e. p/tdocs. But I really am trying, and it doesn't make anything better when you say hurtful things like that. Thanks.
