OCD, an acronym for Obsessive Compulsive Disorder, refers to a mental health condition that affects one in 100 children worldwide. It is characterised by recurrent, unwanted thoughts which lead to anxieties manifesting as repetitive behaviours.
I had really bad obsessive-compulsive disorder. At its worst, I was compelled to leave my house at three o'clock in the morning and go out in the alley because I just knew that the paper-towel roll I threw in the recycling bin was uncomfortable, like it was lying the wrong way, and I would be down in the garbage. / Fiona Apple
