over plucking

I've been addicted to plucking my eyebrows for about 3 years now, to the point where I can't leave the house without drawing them on because I'm completely bald. It's literally an addiction. I've also been attending therapy and psychiatry for OCD, Depression, Anxiety and suicidal/self harm etc so I don't know whether the plucking is just a form of OCD or not. Was just wondering if anyone else has ever experienced anything like this?
