Obsessive–compulsive disorder?

sometimes i feel the needs to squeeze things to get this feeling of unsettling out of my system and i know its gross put i always seem to pick my scabs and chew on them with my two front teeth and spit them out i don't actually swallow because it makes me feel sicking sometimes but i cant remember a time when i let one fall of naturally i pop most if my pimples most of them and scratch allot but i think everybody hates an itch i also pick at my hang nails. i also get intrusive thoughts like sometimes hitting some one who's not even bothering me just because i feel a lil uncomfortable probably a defense mechanism
