I can't stop picking my scalp
I'm 15 years old and I've been constantly picking my scalp for over 2 years. There are periods of time where I stop, but I always come back to it to the point I can't stop. I even do it at school, with my hands dirty or when my nails are too short to properly pick. My mom keeps telling me I should stop, she gets very angry whenever she sees me doing it and tells me my scalp has big red scabs but I don't think they're that bad? Some people definitely have worse ones. Well lately she's been telling me she will slap my hands whenever she sees me doing it, and I really don't care. I'd do it in secret if I have to, it brings me so much satisfaction. But it does hurt when I brush my hair, I'm also a little ashamed of being seen doing it by my classmates (they've probably already noticed) but it's not enough for me to stop.
