20 Celebrities Who Struggle With Mental Illness

15. Billy Joel – Depression

Billy Joel remains one of the most treasured singer/songwriters of a generation, but he stopped touring and making music after falling into a deep depression. He’s said it was brought on by 9/11 and losing faith in humanity, but he was able to fight out of it after learning about the strength and courage of Malala Yousafzai. He has since gone back on tour and wants to make music again.
