I have been biting my nails all my life, but for the last two years, I've been biting the skin around my fingers til it bleeds. Biting my tongue and cheeks til the bleed and swell is also really bad. This one I have started recently: rolling and popping my wrists constantly, mostly my right one. The only way all of it stops is when I'm drawing but otherwise, all these are constant. Is there any way I can get myself to stop doing these things? I've gotten multiple infections in my fingers from biting and also really deep gashes and holes in my mouth, I am afraid that if it gets anymore serious, I could lose a digit or have an actual hole through my cheek. I'm not sure how bad the rolling my wrists is yet.

What can I do?
