Ok, now I want to start out by saying I'm am not sure how long I have been doing this except since I was a young child. I am now 28, I bite my nails to the point that they bleed. In my mind they all need to be the same length and that length is short, I peel the skin around and I have been biting them so long that my nails are actually growing into the skin. I try fake nails and while they work for a time if the nails get messed up before I can afford them again I bite those off, I have tried the nasty nail polish, slapping my self, all kinds of things and I CANNOT get rid of this habit. I do it when I'm bored, when I'm anxious, and I even do and and am unaware that I am doing so. I do not know what to do, I was sexually molested as a child and maybe this is a coping mechanism, or maybe this is a compulsion. I do not know but does anyone else here suffer from it, or have any tips on how to stop it. My nails and fingers would greatly appreciate it.
