I've been doing it as long as I can remember. My parents tried everything to no avail. I am worse when I am anxious or depressed. I have scars all over from it. I am on lamictal (bipolar), buspirone and celexa, but none seem to help. even when I had Ativan it didn't seem to work, though I picked a lot less. for me it is scabs, I can't leave them alone. I often find sores, with no idea how they got there, and no memory of being cut or scratched.
