" The DSM-IV-TR is a 943-page textbook published by the American Psychiatric Association that sells for $99...There are currently 374 mental disorders. I bought the book...and leafed through it...I closed the manual. "I wonder if I've got any of the 374 mental disorders," I thought. I opened the manual again. And instantly diagnosed myself with twelve different ones. "
