extreme picker in search of help

hello, I'm new here. I'm hoping that by sharing my experiences , I'll be able to start breaking my picking habits. I'm 20 years old, and I consider myself an extreme picker; I pop pimples, squeeze out anything that remotely resembles a black head, pick scabs, pull hair, and pick off any callused skin I can find. I want it to stop badly, I'm constantly ashamed of my appearance after picking, yet I continue to do it. I hate that I feel gratification from picking at myself. blackheads and pimples are my two worst problems. I'm covered in scars, everywhere due to the picking. even things that aren't acne, but look like it, I pick. as I'm typing this, I've stopped several times just to search for some slight imperfection on my skin to dig out. before looking up this site, I had been digging into my face in search of black heads. my face and body hurt all most all the time because of the picking, yet I dont stop. I know it's a problem, but I can't quit. I've been picking since grade school and I really want to stop this horrible habit before it takes over anymore of my life. I hope that by joining this site and getting to know others who also have this problem, that I will finally be able to control this awful destructive habit
