obsessive -compulsive disorder/ Obsession

Hate the feeling of having to check things over and over again, I can't stand that feeling. I check my alarm clock at least fifty times before bed. I have an obsession about germs also, I wash my hands constantly through out the day. I excessively worry about things that are out of my control, it literally drives me nuts. So many people I know have some form of it, so Iam not alone, but sometimes it feels as if I am.
