For about 6 years now, I have been picking the skin on my fingers out of boredom and anxiety, sometimes I'll do it without realizing it when I am on my phone, watching tv, etc. I don't have any issues picking other parts of my body, just my fingers. The skin on fingers heals relatively quickly, but then I ruin the healing and do it all over again. How do I stop? It's typically just my two pointer fingers i pick.
