In addition to working on a new album, Mariah Carey is reportedly busy writing her first memoir, “Page Six TV” has revealed.

The singer’s rep confirmed that the book is in the works, and a source told Page Six she’s been “looking inward” and that disclosing her bipolar disorder to People magazine has been freeing.

“There were very few people in her circle who knew [she was bipolar]. It was a very personal decision for her. She’s been on and off medication since she was diagnosed,” a source told us.

After being diagnosed in 2001, Carey revealed to People that she’s currently on medication and has taken control.

“There was a small group of people who really cared for her, personally. They gradually left. There were a lot of issues. It was so layered. It was very, very bad,” a source said.

Carey is currently in the studio working on her 15th studio album and an upcoming tour.

Another source said of Carey’s life, “At a certain point, the truth will set you free. Hopefully, [being vocal about bipolar disorder] will be freeing for her. When you have people that you were close with, like Whitney and Prince, at a certain point, you look inward and come to terms with whatever demons you have.”
