New to me disorder

I found out that my picking is a real disorder. My therapist knows and my old psychiatrist, but my doc was not impressed. It make me feel like I am in control when I am picking. I stop when it starts to bleed. Wearing socks helps my feet heal. One of the reasons for my divorce was from picking the skin on my feet. I don't want this to cause another break-up from any would be relationship. So I pickled the skin off my thumb, stopped when it bled and put Neosporin and a band aid on it. Right now my thumb is pulsating. It hurts. I have chronic pain issues in addition to this. I also have a weight problem. I take meds for depression an anxiety. I think it's all tied together
