In a recent televised discussion about his life-saving heart surgery, late-night talk show host David Letterman confessed he takes medication to battle depression.
The TV personality joined comic Robin Williams and former President Bill Clinton to talk about his second chance at life as part of a Barbara Walters news special, which aired on Friday.
But they didn't last long.
During the segment, Letterman stated, "Depression is a black hole ... I've dabbled in it.
"There's a difference in being sad and being blue and being depressed and being chemically or clinically depressed. I do know the difference between those and it's horrifying.
"Without some kind of medicinal help ... institutions used to be full of people who were depressed."
Asked if he was on meds himself, Letterman said, "Yes, I'm on medicinal help."
