Do I have OCD? Please help it's affecting my life!?

I can't use other peoples dishes at their house because I feel lyk they are dirty. I'm constantly washing my hands because if I don't then I won't do anything until I do. The thought of using a dirty dish or eating while my hands aren't washed gives me the heebie-jeebies. I have to rewash all dishes I use and I have to clean everything that I touch.
