The longtime host of NPR's Wait Wait...Don't Tell Me has battled depression for much of his life but has never gone public with that struggle until now. Sagal recently went through what was for him a very painful and very messy divorce. He shares how he's been able to move on and host a weekly comedy program even as his life was falling apart. Some of the methods: keeping very busy and listening to Amy Poehler. We also hear from Peter Sagal's friend, the neuroscientist Daniel Levitin, on what helps and hurts a depressed person's brain in times of crisis.

A sneak preview of some of the voices you'll hear on the upcoming season of The Hilarious World of Depression. Host John Moe talks to some of the top names in comedy, who share candid conversations about their experience with depression and have a few laughs along the way.
