I'm 19 and I've been biting and picking at the skin around my nails, my cuticles and my nails for as long as I can remember. In fact it's been going on so long that the skin surrounding the nails on my thumbs is always a pink color as the skin is never left long enough to match the lower part of my thumbs. I've also learned that this behavior is hereditary with the women in my family, I've been told that my Great Grandmother even was a nail and skin biter. I seem to have minor forms of everything, none of it embarrasses me too much, except for the nail and skin biting around my fingers, but only if I'm meeting new people. I also pick at my scabs, I have one on my shin right now that's been trying to heal for a month, but usually every night before I got to sleep I pick the scab off. I usually get scars when the scabs finally heal. I have hereditary skin condition called keratosis pilaris, a build up of keratin proteins on the skin on my upper arms that cause little dry bumps and I constantly pick at these especially the ones that are near my elbows, they become inflamed and often bleed. I've also experienced standing in front of my bathroom mirror for hours late at night trying to get rid of my blemishes and blackheads. I also think I might have a mild form of Trichotillomania, in Middle School I would frequently pull hair from my part especially if they felt 'wrong'. I stopped for the most part in high school but now that I'm in college I've found myself pulling the 'wrong' feeling hairs more and more often.
