Demi Lovato is receiving an outpouring of support after detailing the severe health complications she experienced as a result of her 2018 drug overdose.

On Wednesday, the official trailer for an all-new documentary titled Demi Lovato: Dancing with the Devil, which chronicles her battle with addiction and the aftermath of her public struggle, premiered on YouTube. In the upcoming docuseries, the "Anyone" singer revealed she suffered three strokes and a heart attack during her hospitalization — adding that she "was left with brain damage, and I still deal with the effects of that today."

On Twitter Friday, Christina Aguilera was among those to write encouraging words to the star, 28. "The ability to share, stay open, stay loving and show vulnerability is not only a strength of yours Demi, but a gift of an endlessly talented woman I love and respect. Keep shining my love ☀️."

Lovato expressed her gratitude for the sweet message, writing, "Love you @xtina 💞 Thank you for always supporting me and being a part of this. Calling you a friend means so much to me."

Fellow singer JoJo simply wrote, "My girl ❤️. I love u!" To which the "Still Have Me" singer responded, "Love you too @iamjojo!!"

The endearing messages continued pouring in, with actress Jameela Jamil adding, "Man, Demi Lovato is so strong that it's obscene. To withstand all of this and then to be giving enough to talk about it publicly... is 🤯❤️."

On Wednesday, Lovato told PEOPLE during the Television Critics Association panel for the docuseries that she was owning her experience and "wouldn't change a thing."

"Everything had to happen in order for me to learn the lessons that I learned," she said at the time. "It was a painful journey, and I look back and sometimes I get sad when I think of the pain that I had to endure to overcome what I have, but I don't regret anything."
