Carey, 48, told the magazine when she was first diagnosed following a physical and mental breakdown in 2001, she “didn’t want to believe it”.
“Until recently I lived in denial and isolation and in constant fear someone would expose me,” she said.
“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.”
She says in her time battling bipolar II disorder, she has sought treatment in the form of therapy and medication, adding that for a long time, she was instead convinced she had an issue with sleep and nothing else.
