Do you think this is OCD? Or something else?

I have OCD mine is avoiding germs. I think you have OCD. What you have described is your Obsessions and Compulsions. I would tell someone or you will keep on doing it and possibly add to your list of compulsions and obsessions. Unless you can make yourself stop but if that was the case I'm sure you would have tried already. It takes a lot of time and energy to be OCD physically and mentally. What you described is not silly and you don't want it to take over your life.
