OCD Pimple Popping

Hi, i'm new, im 16 years old female, i have a problem. I can't stop popping, peeling, scraping, scratching, and squeezing any pimple blackhead or any kind of dried blood scar and crap on my face. Im a junior in high school, i've tried for years on cures and remedies and methods to stop. doctors have recommended advanced treatments to subdue my acne as well. But nothing even reduces it by 2 %.  my skin just absorbs the medication and gets used to it very quickly. But the ones that come new and if i see the pimple....i just get the urdge and i know its there i'll pick and pick and then pop it. my face now looks like it has red paint splattered all over it. it also spreads down my whole body my chest and back arms and legs and occassionally down there. Please i'm asking for someone who maybe who knows how i can be helped even a little. i've been fighting this since i was 9 going on 10 its been so hard and i just want to look at least a bit normal come my prom or even pictures. please someone help me. I'm begging you.
