Earlier this month, Carey opened up about her struggle with bipolar II disorder. In an interview with People, she said, "Until recently I lived in denial and isolation and in constant fear someone would expose me," she said in the interview. "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."

The mom of two said she came out publically about the disorder in order to lift the stigma associated with mental illness.
