I have obsessive compulsive disorder i think. so do i need to see someone?

Do you want help?: If obsessive compulsive disorder (ocd) symptoms are bothering you enough to interfere with your life, then yes -- seeing someone would be wise. Your asking this question shows that this is on your mind. Why suffer longer than you need to, when helpful treatments are available? You can contact a psychiatrist, psychologist, or other therapist; they'll be glad to assist you.
