Scared people will notice my ocd

I'm really worried my friends are starting to notice my ocd. I havent told any of them because i'm scared they'll think i'm lying or being attention seeking. One friend in particular is noticing how much i wash my hands and have to repeat stuff, so to stop her asking i made it into a joke and know if i tell her she won't believe me. It's really interfearing because i can't stop thinking of everything i've done today and wether i've done or said anything they could guess from. I feel really stupid like i'm faking it. should i tell someone or what?

thanx for listning, immy
