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 "If It Makes You Happy" rocker is in a good place now, but several years ago, she suffered a debilitating bout of depression that lasted six months. "During some of those darkest days, I'd hardly get out of bed and just the phone ring and ring," she explained in 2003. "Small problems became insurmountable, and so I shied away from normal behavior. It seemed easier to duck out of life that way...It was a very bizarre, exhausting, and dark time."
