Living with Obssesive-Compulsive Disorder

I am a 56 year old female who self diagnosed my problem. Seeing a psych for over 25 years doesn’t enter into this issue. OCD wasn’t even a diagnosis when I was a kid. But the things I did, and continue to do, have affected my entire life. I am embarrassed by the constant scratching, picking, pulling of my hair and face. Pulled out my eyebrows when I was 13.. pulled my hair for several years in my 40’s.. luck had it where no one knew and I have very thick hair. I would wake up in the middle of the night with a hand of hair.
If I am not quite awake, just dosing, I find myself picking, pulling, pushing, anything on my face that shouldn’t be there. It has escalated so much that I am embarrassed to leave the house. I do leave, but with makeup covering the abuse I put it through the night before.
I can say NO, over and over again and
find myself chasing some knot on my face. I am afraid. I am afraid the shame of this and the obvious scars it is
leaving will drive me to a depression I will not bounce out of. My doctor is treating me for depression anxiety, and ADHD. When I self diagnosed this issue he went on line and prescribed something that didn’t make any difference, so I stopped taking it.
I need support to get control of this before I do something i cannot take back. I have had symptoms for my entire life, but I thought I was just crazy, or stupid, or whatever it is you tag a kid that does stupid things like pick his or her face. I need someone or a group to talk to and get this in check. I seem to enjoy the healing with peroxide and neosporin, and aloe plants. The pain doesn’t bother me although it should. I am really concerned that I can’t stop. Help .
