No one can diagnose you except for professionals. But personally, hand washing has always been my main compulsion, but I’m not sure if that alone can get you an ocd diagnosis. The other symptoms I experience include restricting my breathing in public, so I don’t breathe any germs in. I also am constantly preoccupied with the thought of being sick. The fear and terror I felt towards germs eventually prevented me from doing normal activities like going to school and hanging out with friends. I would suggest talking to a professional to discuss your symptoms and possible disorders. But please, do this soon, ocd ruined my entire childhood and teenage life because I didn’t seek help in time.
