What did you do when you had/have ocd?

ok i know i have ocd. but i just want to make sure ido. so when i was 4 years old i had an ictch on my arm so i scratched it then on my leg but before i scratced my leg i had the urge to scratch my arm even though it wasn't itchy. then my neck itched so i had to scratch my leg then my arm then my neck. so anyway as years ped i did more ocd-ish things. constinatly counting in my head. cracking my head backwards 3 times.splashing my face with water depending on my age.(12 years old 12 times 13 years old 13 times) and other things. so on tv when i was 13 i found out i had ocd from watching a show with ppl with ocd. so i told my mom and she said i was just being silly.i told her 3 other times but same response and it frusrating me. 3 years later still kinda have it (bugs the crap out of me when my bookshelf and counter in my bathroom are unorganized) but that's pretty much it. for the past 12 years have been true frustrating hell. so what ocd things do you do?
