OCD

One of the worst mental illnesses to exist, something the devil himself pulled out of his asshole to torture all of us. It's repetitve behavior to fulfill whatever your compulsively thinking about. For me it's washing my hands a.k.a fear of germs. I can't even touch my dog unless I wash my hands afterwards. It's an embarrassing disorder to live with and people will think you're crazy and bizarre. Some will have sympathy for you if they aren't an asshole, having such compulsive behavior can make you very hot and bothered and also others around you very annoyed and overall just depressing.
