For years, I've had this OCD-like symptom of being compelled to pick at my skin-- at scabs, acne, dry skin, etc. I know that it's gross, and I know that lots of people pick at their acne to some extent, but I do so more than most people. It's an obsessive thing that I feel like I can't really help. Over the years, I've obtained many scars from this awful habit. I'm pretty ashamed. I hope the scars will heal someday, but I don't have much hope of that.
