I have done this cuticle picking since I was a kid, I'm 54 & still do. So you are not alone there & it is worse when stressed. Still drives my mom crazy & she's 78 & just won't let it go. When I go for a visit & we're watching tv it annoys me cause she doesn't understand that I HAVE to do it! My husband does though, bless him.
Never thought I'd be ever be discussing this with any one, it's kinda personal... Also didn't know it was an OCD thing, just learned something new!
Hope you enjoy your time here, I'm new too & it's really been helpful for me.
Take care & look forward to your posts.
