I pick my scalp obsessively, but I only do it about once a year or every two years. 

I take Zoloft and it really helps me stop picking. I only pick when my anxiety is so bad that I HAVE to.

I’m actually currently having a picking  episode. When I do pick I pick until it gets so infected that I have swollen lymph nodes, and  there’s  nothing but pus oozing out of my wounds. I then go to a doctor, and get it surgically cleaned because the infection is so bad. They then give me topical antibiotics and it’s so oily and slippery that I can’t pick.
