never diagnosed but convinced i have it

i have had an issue for over 10 years with picking at the skin on my feet. i have always had dried/cracked heels even as a teenager and started picking at them when i would have to spend the weekends with my dad. now, at 26, i have a compulsive problem where im almost ALWAYS picking at my feet and not just the heel. around my toe nails and the soles of my feet too, to the point of bleeding. i have recently been diagnosed with OCD as well and have brought this issue up to my psychiatrist/therapist as well but never really worked on it aside from that. i notice it happens most when im bored or stressed. i try to keep socks on my feet and my nails short but nothing helps and sometimes i don’t want to stop. i pick other areas as well like my face or arms but people can see those areas much easier so i tend not to go over board unlike my feet. i don’t know how to navigate this or where to even start to stop this but i hate my feet so much and im so embarrassed of them 😭😭
