messed up fingers

I'm new here. I never knew there was a name for what I had. I always blamed my picking and chewing at my fingers on a habit. Never would I have thought I could be suffering from an OCD. I did suffer from some abuse as a child and I have gone through depression a few times. I've never been treated and keep my thoughts pretty much to myself. I am going through a lot of stress right now and my hands are suffering from it. I can't stop. It feels like the only control I have in my life right now. I hate it. Even my kids keep telling me to stop. I have been doing this for as long as I can remember, I'm 47. I teach science in high school and we talk about these types of things. I don't tell them about my personal experiences. Thanks for listening.
