I had no idea this affected so many!!

I was watching "Obsessed" on A&E tonight and one of the women compulsively picked her face. I had NO IDEA this was a disorder. For years I have picked my face, my fingers, my toes, my feet. My face looks terrible. Scabs and all manner of gross things. I pick off the skin on the bottoms of my feet until they bleed and it hurts to walk. I pick my finger nails and toe nails and the surrounding skin until they bleed and get infected. I'm very embarrassed about my face and feet especially but just thought I was wierd. I already have depression and an eating disorder and don't want to think about adding another diagnosis to the mix. I'm incredibly embarrassed about the whole thing. I would love to get help but now that I know it's actually a type of OCD, I'm afraid to seek help for it because I'm tired of mental health issues. Has anyone been in a similar situation or been able to get over it themselves? ~Katie
