Demi Lovato has recently revealed her health issues in a trailer of a new YouTube documentary called “Demi Lovato: Dancing With the Devil,” which debuts March 23.

It seems like the 28-year-old singer is ready to share what really happened when she was undergoing treatment for a drug overdose in July 2018 and how it left her with brain damage, according to LA Times.

In the trailer, which dropped Wednesday during the virtual Television Critics Assn. press tour, Lovato said, “I’ve had so much to say over the past two years, wanting to set the record straight about what it was that happened.”

“FYI, I’m just going to say it all, and if we don’t want to use any of it, we can take it out,” she adds. “Any time that you suppress a part of yourself, it’s gonna overflow.”

Lovato has been open about her struggles with her physical and mental health and her sobriety. She reveals in the trailer that her doctors told her she had three strokes and a heart attack. The singer went on to say her doctors told her she had “five to 10 more minutes” to live when she was hospitalized for a couple of weeks before entering an in-patient rehab facility.

Of course, Lovato survived and told interviewers that, just like her cat, she’d had a lot of lives and now she was on her “ninth life.”

On Wednesday, Lovato told the Associated Press that she still was dealing with the effects. She said, “I don’t drive a car because I have blind spots in my vision. For a long time, I had a really hard time reading. It was a big deal when I was able to read a book, which was, like, two months later, because my vision was so blurry.”

In the trailer, her stepfather, Eddie De La Garza, says, “Demi’s very good at making you believe she’s OK.”

She was also the subject of a 2012 MTV documentary and a 2017 YouTube documentary, in which she spoke about her cocaine and alcohol addiction.

The documentary, directed and executive produced by Michael D. Ratner, also explores how Lovato is harnessing her power and rebirth, and touches on her short-lived engagement to Max Ehrich that ended in September,” according to LA Times.

Lovato said, “I’m not living my life for other people or their headlines or their Twitter comments.” The story was originally published Wednesday in LA Times.
