Mariah Carey has just revealed to PEOPLE Magazine that she was diagnosed with bipolar disorder in 2001.

“Until recently I lived in denial and isolation and in constant fear someone would expose me,” she says. “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.”

Mariah is reportedly currently in therapy, and she’s said to be taking medication for bipolar II disorder which involves “periods of depression and hypomania.”
