A friend of mine was recently diagnosed with OCD or obsessive-complusive disorder. Have you heard of it?
Yeah, a lot of people claim to have it even though they are just self diagnosing. 
Yes, she has quite a severe case of it. She feels the need to check things repeatedly and perform certain routines over and over. She really struggles with it.
Damn that sounds like a huge hassle.
She obsessively washes her hands, counts random items and checks to make sure her door is locked at least twice an hour. She can't control it.
