Finally Reaching My Hand Out for Help

Hi. I don't know exactly where to start. I have been since what seems like forever. Now that I am 15 years old, I am starting to realize how big of a problem it is. I constantly pick; there seems to be no "rules" to this behavior. No matter where I am, whether it is sitting in front of the mirror or at school or with my family, I cannot stop. My face is scarred, my mother notices and joking tells me she will remove my hands if I keep picking, haha. Though I know she is joking, I wish she would. I know I pick and that fact I would think would want to make me stop, but I can't and I hate myself for it. I just want out. I have been doing a little research on this behavior. I guess there is quite a few causes for it. I have not been to a doctor yet, but I have a theory for my behaior. My mom when she was in college had trichotillomania, or hair pulling. Both of our behaviors are considered a type of OCD, apparently, and OCD tends to be genetic. Anyone else have a similar story? Anyway, I am just looking for some help. I feel trapped in this situation and all I want is for this to stop. I guess I might actual have OCD, since the entire time I was typing this I have been checking my spelling and rearranging my words. I am looking for someone to talk this through with, or at least just a little advice about it all, including what to do when I do see the doctor. Thanks. ~Shadow
