28 with dermatillomania since i was 2 years old. is there hope??

it's centered around my face, particularly my lips. every now and then i'll have a period of several weeks where i become laser-focused on a specific area and pick at it to the point of bleeding. it's been this way since i was a toddler, and i have never formally received help for it (though my lovely mother did like to punish me for doing it and yelled at me constantly about "ruining my face" and "making myself ugly" lol).

right now The Picking Spot is at the left corner of my bottom lip, and it's an absolute scabby mess. i've cut my nails super short, have menthol chapstick handy at all my sitting spots, and even wear a bandage over the spot at bedtime so i don't pick in my sleep, but it's barely helping and i keep going back to square one every time it tries to heal.

what are some good coping mechanisms i can try? any support is welcome, even moral lol. i feel so gross bc it def looks like a cold sore or something. embarrassing as hell whenever this happens
