Obsessive Compulsive Disorder is a human anxiety disorder that causes those affected by it to disrupt their daily life by getting caught up in patterns. For example, the urge to turn the light on and off 33 times before you leave any room. It is not a very well understood disorder, and can be very difficult to live with. Oftentimes, you will hear someone make a joke along the lines of “oh yeah, I’m so OCD about that”.
