Is this OCD? Or am I just over-reacting?

Sounds like OCD and I know how annoying it can be. I told my mom about it and she didn't seem to take it seriously (I suggest you tell someone about it). So I decided since I thought it wasn't that strong, I would try to stop it myself. I read online that it can be bad if you try to stop it by yourself because the anxiety would worsen and you might end up with psychotic episodes. What I did, when the obsession comes, with the corresponding task, I don't do it. I remind myself that it's OCD. Think, "I can't let you control me. This is my life. I'm in charge." If it still doesn't stop and you feel it's getting worse, go see a therapist and be honest. You seem to have the will to fix it and that's important. OCD can be really energy-draining and can prevent you from doing things that can help with life progress.
