Struggling with Hair Picking

I struggle with picking at my hair. I pick the split ends, scratch individual strands until they break off, and pull from the root if it didn’t ~feel right~. I have naturally thick hair so it isn’t noticeable just by looking (to others) but I can tell that I am loosing length, it’s shorter than when I got a haircut in May, and I can fill how thin it’s getting. i’ve tried meds, I put my hair up just to take it out, I tried knitting and crocheting, but I cant stop. my fingers bleed from picking so much, im covered in piles of hair. it’s embarrassing
