Do you feel you have OCD? I know with me when my anxiety gets very bad, my OCD starts reappearing. I do not touch any door handles with my hand because I do not want to catch anything from others. Whenever I close my dorm door I second guess myself that I actually closed it, so I start to worry about that. All the way down to the minor things, like having a paper being straight on my desk, or having everything in a specific place in my dorm.

It seems to me like you have some OCD tendencies, that could be helped by medicine and some therapy. Some medications for OCD also help with anxiety, so it could help you out overall.

Best of luck to you, I hope you start to feel better
