A Day in the Life of an 'Obsessed' Man (VIDEO)

A man who suffers from obsessive compulsive disorder shows the severity of his affliction in this clip from 'Obsessed' (Mon, 10PM ET on A&E).

The man, a musician from Chicago named Chad, suffers from ritualized, obsessive behavior that involves, among other things, the turning of doorknobs, compulsive rubbing of his hands, and the rinsing of his toothbrush a specific number of times.

"It's really embarrassing," said Chad. "It's like you're weak. You're not a full human somehow. You're playing with 53 cards in a deck. You know what I mean? One too many."
