I'm 14, I've been picking at my scalp for a couple years now. I don't really do it in times of stress, or sadness, etc, I do it because I enjoy it and no one seems to understand it. My mom will tell me to stop because of the sound it makes when I pick at the scabs, and even then I can't stop. I do it in school, in the car, watching TV, etc. It takes me loads of time just to be able to pull my hand away from my head and to my pencil to start my work. It doesn't hurt, and I like it, but I feel like something is wrong with me and I'm just so tired of it. No one else I know does it, I feel like I can't talk to anyone.
