"Is this going to be it for me, am I going to be spending the rest of my life writing about cataracts and hemorrhoids... and... . just not what I wanted to do, and I was just intensely depressed all the time."
His publicist said that the star died on Sunday (4 February) while in hospice care in Chicago.
