The 48-year-old says she lived in denial and isolation and feared someone would expose her.

Carey is in therapy and taking medication for bipolar II, which involves periods of depression and hypomania, which involves irritability.

Carey says she’s taking medication that’s not making her feel too tired or sluggish.

Carey says, “I got back to doing what I love — writing songs and making music.”
