I have the habit of peeling my skin off my lips and fingers. And is painful and most of the time it bleeds. Even though it heals with time, i do the same again until it bleeds and, i find myself doing it every single time. I have tried to be aware and distract myself but it never worked. For a few years it's been happening i thought it was because of dry skin but i tried ever oitment given by dermat but i developed this habit and many a times it's really hard to control. Everytime i see a lil skin coming off i peel it doens't matter if it pains or not
