It's a condition where I bite the skin around my fingernails until they bleed. My fingernails are deformed as I have damaged the nail beds. It's an OCD condition but I think it is really a subset of the Bipolar II and CPTSD with Psychotic Features - an anxiety mitigation strategy that of course causes more anxiety. I do it subconsciously and it's really gross.

Anyone any thoughts on how to knock it on the head?
