Mariah Carey Reveals She Has Bipolar Disorder In a new cover story for People magazine, Carey revealed that she was first diagnosed in 2001 after she was hospitalized as a result of a breakdown. Until recently I lived in denial and isolation and in constant fear someone would expose me. It was too heavy a burden to carry and I simply couldn’t do that anymore. I sought and received treatment, I put positive people around me and I got back to doing what I love — writing songs and making music. Carey told People that she is still in therapy and is taking medication for bipolar II disorder. She would go on to say that she shared her diagnosis because she’s “in a really good place right now.” "I'm hopeful we can get to a place where the stigma is lifted from people going through anything alone," It can be incredibly isolating. It does not have to define you and I refuse to allow it to define me or control me."
