Demi Lovato, Catherine Zeta-Jones, Jon Hamm, Carrie Fisher, and Ashley Judd are among the many celebrities who've admitted to struggling with depression, anxiety, or bipolar disorder
The Disney star checked into rehab in 2010 for "emotional and physical issues" including bulimia, cutting, and bipolar disorder. "I had no idea that I was even bipolar until I went into treatment," she revealed in 2011. "I was conquering the world, but then I would come crashing down, and I would be more depressed than ever."
