i wash my hands constantly, must have a full ammo magazine in FPS games at all times, cant stand not wearing a shirt (makes mah back feel funny without a shirt on), cant stand people watching me play video games in person, like, over my shoulder and shit, and, i must always have full health in a video game, no matter what.
Same for all of these things except for the full-health part.
I'm pretty sure you have OCD.
