After revealing her battle with bipolar disorder, Mariah Carey is now writing a memoir about her life.

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

The source also said at one point the symptoms of her diagnosis affected her relationships.

“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.”

The mother-of-two went public this week with her diagnosis, which she was first diagnosed with in 2001.

“Until recently I lived in denial and isolation and in constant fear someone would expose me,” she said in an interview with PEOPLE. “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.”

Mimi is also working on her 15th album. No word on when her memoir will be released.
