this is a compulsive disorder that causes body-focused repetitive behavior to your skin (by gnawing or eating skin), typically around the cuticles of the nail and affects 1 in 20 people. i've been doing this since my childhood and it's been almost impossible to stop. i don't eat my own skin but i will dispose of it after tearing a piece off. i don't usually go too far, but occassionally, i will "accidentally" give myself small open wounds on my fingers. when people see me doing this, they might scold me for it or tell me to stop but i fucking can't! i don't even want to be treated to help this, it's like the only way i can cope with anxiety or stress, otherwise i'll just blank out/dissociate. i don't wear bandaids much really so it's kinda out in the open sometimes if my finger's bleeding. but if that happens, i try to go immediately wash my hands throroughly in fear of contamination. it's really embarassing when people ask about it or seem concerned. i don't really see it as too much of a negative impact on my life besides how people react or whatever. is this common with people with BPD? i think i might've read somewhere that compulsive behaviors similar to Dermatophagia are common with BPD sufferers?
