Earlier today, Mike Tyson stopped by the SiriusXM Studios in New York City to make an appearance on The Howard Stern Show. And during his interview with Stern, he talked about his lifelong battles with mental illness, depression, and drug addiction. Stern also asked Tyson his thoughts on the late Robin Williams, who dealt with depression and drug addiction as well. And the former boxer revealed that he knew Williams and spoke with him somewhat frequently about their demons. He touched on his thoughts on suicide, too.

You can hear a short clip of the interview above. Sad stuff.
