I don't know what is wrong with me. I have heard I may have OCD?

It sounds like you most likely do have OCD or some version of it. I feel like I have OCD sometimes, because I need to touch things evenly and for other reasons. (an object isn't straight, etc) You are not going crazy. I have asked my friends and family if they ever feel like they have OCD and a lot of them have told me yes.
