My OCD is starting to hurt me...?

i cant stop myself from saying religious terms i learned as a boy like amen Jesus' or stop myself from tapping my fingers three times or blink 10-15 times, because if i dont i feel like i might get into trouble or worse yet - my family also, i know many other people have this problem too but i just discovered i had it about a month ago... but now i feel like "a freak" and i want to stop because im having like a overload in my brain and am having minor headaches now - how can i stop it or at least like "dull it"?
