Demi Lovato has long been open about her experiences of mental health issues, substance abuse and self-harm. The 24-year-old singer, who first found fame aged just 16 in the 2008 Disney movie Camp Rock, entered rehab in 2011, where she was diagnosed with bipolar depression and treated for bulimia.

Ever since, she has made a point of speaking frankly about living with bipolar depression – the depressive phase of bipolar disorder – in the hope of shattering the stigma that surrounds mental illness. Already a spokesperson for US mental health charity Be Vocal, she is now adding another string to her advocacy bow: that of film-maker.

Lovato served as executive producer on new film Beyond Silence, which explores the true stories of three people living with different mental illnesses. And in a new interview with Ellen DeGeneres, the musician discusses her relationship with her own mental health.
