TONGUE?

Hi, I'm 21 years old and I have picked my skin for as long as I can remember. I have ALWAYS peeled the skin off my fingers. Every single finger I have is constantly red and bloody from the tip until almost my second/middle knuckle. I pick them until they bleed and I just can't stop doing it. I didn't know this was an actual condition until a few years ago when I saw an episode about it on television. You can't even believe how relieved I was - I thought I was the only person in the world partaking in this disgusting ritual. Sometimes I pick my fingers with a pair of tweezers, most of the time just with my own nails. Sometimes I will sit in one place for an hour just peeling my skin away until it bleeds and bleeds. Sometimes the urge to pick is SO BAD that I don't even CARE if someone else is near me and sees me doing it - I just can't stop myself. I need to pick. No matter how ashamed and grossed out with myself it makes me. When I was a little girl, I also used to pick at my toes/feet, and my scalp until it bled. But what gets me the most is that when I was young I would peel the skin off of my TONGUE!!!!! I stopped doing that when I was still young, thank god. Has anyone else done this before? Picked their tongue with their fingers or teeth until it bled???? If that's not messed up I don't know what. is.
