In Lovato's new YouTube documentary, Simply Complicated (which debuted on October 17) she stands in her truth about what happened behind the scenes, ever since she sought treatment for the disease years ago.
"I loved it. I felt out of control with the coke the first time I did it".
In Simply Complicated, Lovato is honest about what she's learned in the last decade.
In an interview with Billboard.com discussing the YouTube series, she said: "I think what was hard about the process was being honest about where I am in my life today. Nobody knew." Other vignettes include performing hungover, with the singer recalling, "I was so drunk, I vomited in the back of the auto service on the way to the airport to perform on American Idol". She's talked before about struggles with being bullied, mental health, eating disorders and other issues.
It's like Demi tweeted in 2009: "No matter what we go through, and no matter where we are, nothing and no one can change our friendship".
"I've never loved anybody like I loved Wilmer and I still love him".
She wrote "Recovery is possible" next to the image, following her recent battle with her own eating disorder. While she's doing better now and hasn't used in five years, she discusses her ongoing struggles with eating disorders; she's in therapy and spends regular time meditating and working out in order to keep her life on track.
Lovato also said in "Simply Complicated" that she doesn't identify as straight, and that she uses a dating app that features both men and women.
Demi ends the documentary by talking about her connection with her fans and saying it's the most important part of her career.
Demi Lovato is opening up like never before. "Body image, what I'm going to eat next, what I wish I could be eating, what I wish I didn't eat", she said.
In a follow-up comment, Sel added, "Love you".
