You are going to think I am a freak for what I do but anyways here it goes: For years now, I have been biting the middle part of my middle finger to the point where it has turned into a huge callus like thing there, and basically looks disgusting. I bite it constantly, usually without thinking, and more when I am nervous or very into a task. Ive tried everythign to stop, including putting Band-Aids and covers, but end up biting them, removing them, or when I remove them to see if they worked I start biting it immediatley. Everyone noties this already and I have no idea what else I can do?? Do you have any suggestions, preferably ones which do not involve outside help?
