Clarkson, 32, who gave birth to a baby girl seven months ago, said she was getting frustrated over her vocal loss, reported Ace Showbiz.
"Afterwards was the part where I literally had a moment where I cried and drank wine all day. I was like, 'Oh God, I'm not going to be a singer anymore'.
"I was bawling to my husband and completely hammered, just going, 'Oh my God, it's over. I don't know what I'm going to do I guess I could do more charity work.' I didn't know what I was going to do," she said.
Called Piece by Piece, the album is a follow-up to 2011's Stronger.
