After the news came out yesterday that Robin Williams died of an apparent suicide, Marc Maron reposted his WTF episode that had long been archived and behind a paywall. As Maron says in a new, very affecting intro, "It changed my life and it changed many people's perception of Robin Williams." Released in April 2010, Williams was incredibly candid about his struggles with depression and addiction in a way that we've never heard before. It is an intense, powerful, truly sad must-listen.
