Late Show host Stephen Colbert says he's suffered from severe anxiety, but performing for an audience has been a key to overcoming it.
Colbert told Rolling Stone that he once had a nervous breakdown, not long after getting married in 1993. It got to the point he required medication. But when he was on stage, Colbert said the anxiety melted away, if only for a short while.
Since then, he's learned that getting others to laugh is the linchpin to his mental health, and he hasn't stopped since.
