I scratch too. I sometimes do it with a knife....I haven't cut though. Mostly because I'm too scared to draw blood and make a scar. I work in a hospital and don't want people to think I'm crazy. That way I can blame it as i bumped into something. I agree though....not healthy. And I used to do it when I was little, and now at 27 years old....I've been going though some things and started again. My husband has started taken notice. I told him, and he is very supportive and he is going to help me find help for this. Tell someone! I feel a huge relief now that my husband knows and is not judging me.
