Demi Lovato suffered from depression along with her eating disorders and self-harming tendencies. She also had sudden fits of anger, and in one such fit, she punched a dancer. This prompted her to go for therapy in November 2010.
After recovery, she admitted to have had resorted to ‘self-medication’ with drugs and alcohol for the pain. Her anorexia and bulimia were accompanied with depression and bipolar disorder. In 2012, MTV aired Demi Lovato: Stay Strong, a documentary about her struggles and success.
