Whats happing to me ? i'm hurting my self?

Oh my Zeus, that must be terrible. I'm kind of in a similar situation; I have dermatillomania which is basically compulsive scab picking and I have an obsession with breaking off any damaged ends of my hair and pulling out any that don't look "right." It used to be TERRIBLE, I would be pulling at my hair all the time, ALL THE TIME, but Zoloft has really done wonders for that. The skin picking's still a problem though :/ Okay, here's what you need to do: tell someone you trust who is in a position to help you or to get you help. You need a psychologist or mental health social worker, and a psychiatrist to order meds for you. I know you don't want to be on medication at thirteen years old, but trust me, it will make a big difference once you get the on right one or ones. I would suggest putting band-aids over the places you pick at most often, and wearing long sleeves, because you're less likely to pick if getting at your wounds is a hle. I know how hard it is to stop, but I think that if you do the right things and make enough of an effort, you can at least reduce it a lot. As for telling your mom, just sit down and talk with her about it. It's a scary thing, telling someone you have this kind of problem and you can't control it on your own, but in the end, it'll be worth it. I wish you the best of luck! <3
