I don't cut. At the most, I just squeeze a knife in my hand for the pain sensation; I don't break the skin that way. However, I'm a horrible picker. All over my back, scars and the like. Sometimes my fingernails are covered in blood. I have some pretty bad scratches on my ankles right now. Doesn't hurt, but looks bad. Can't stop. My only explanation is that I like pain. Or maybe I hate myself and the pain makes me feel better? I don't know. Only some of them are visible, very faint scarring on my neck. Mostly I try to contain it to my back and shoulders, where it isn't visible. Sometimes, very small bits of skin get pulled off. I'm worried I'll never be able to stop scratching and picking.
