I think i have OCD. Please help.?

The most important thing you can do is get a proper diagnosis. Once you are properly diagnosed, if you do indeed have OCD, you can do something about it. It you do have OCD...the first thing you should do is ERP (Exposure Response Prevention Therapy). There are medications out there that can help you as well, but ERP has proven more successful than medication alone. There are psychologist who specialize in ERP.
