Heyy, I'm gonna jump in here. Don't worry about sounding crazy because your not. Sounds like anxiety related to OCD which a lot a people suffer with. The nice thing about anxiety disorders is that cognitive behavioral therapy is effective for many people. Some never use meds, it is all dependent on the person. You do need to speak up, however, anxiety tends to progressively get worse without treatment. This is nothing to be ashamed of, if it helps chalk it up to biological brain imbalances, because that is a large part of it anyway! Best of luck!
