Demi Lovato is opening up about her personal struggles with her health and addiction in her new docuseries.

"I had three strokes. I had a heart attack -- my doctors said that I had five to 10 more minutes," Lovato says in the official trailer for her new docuseries, "Dancing with the Devil," released Wednesday.

It's not clear if at that moment she's speaking specifically about her near-fatal 2018 overdose, though one friend is seen commenting, "She should be dead."

Later on, that same friend says, "Are we talking about heroin? Are we doing that?"

Eager to set the record straight, at one point in the trailer Lovato tells the filmmakers, "FYI, I'm just gonna say it all, and then if we don't want to use any of it, we can take it out?"

The trailer also features snippets of a new Lovato song, also titled "Dancing with the Devil."

The four-part docuseries, which features contributions from the singer's family, her pals and her famous friends like Elton John and Christina Aguilera, premieres March 23.
