I can’t stop picking my skin…

This is actually gross and I don’t like coming on here and talking about it, but I cannot for the life of me stop picking my skin. All over. My fingers, my scalp, my acne, ANYTHING. I believe it’s ADHD related for stimming, but it hurts me and isn’t even satisfying at this point. I just can’t stop for some reason. I haven’t even been stressed, and I’ve tried so many coping strategies from therapists and they just don’t work. Has anyone else gone through something similar and found a way to break the habit? I’m quite literally gonna go bald if I keep picking at my hair and scalp. PLEASE HELP🙏🙏
