I worked thru a book that really helped me. it was called the scarred soul. you can get it on amazon. you read the chapter and answer the questions at the end kinda like a journal type thing. it helps you to understand why. it is very non threatening and doesn't ask you to stop cutting until nearly the end of the book. I had to quit then because I wasn't ready to make that commitment but I didn't cut for five years having worked that far. I only cut a few times having had a nervous breakdown and being very suicidal and now I haven't cut for seven. I still think aobut it but it is fairly easy to resist. check it out. I am sorry you are struggling so much. take care.
