In June, Lovato released a single, “Sober,” detailing her relapse after six years of sobriety. Prior to the song’s release, Lovato had said on Twitter that she was preparing to share her truth with her fans through her music.

There’s nothing like the truth. The honest to God, uncomfortable and shocking truth. Sometimes you have to share your story in the most honest way possible… for me that’s through music

“There’s nothing like the truth. The honest to God, uncomfortable and shocking truth. Sometimes you have to share your story in the most honest way possible… for me that’s through music,” she tweeted in May. “Sometimes you have to end an era to begin talking about a new chapter of your life.”

Lovato has been open about living with addiction, her sobriety as well as her mental health. In March, she told Dr. Phil that she experienced suicidal thoughts as early as seven years old.
