Demi Lovato shares her personal struggles in her new documentary Simply Complicated, which premiered on YouTube today (Oct. 17). The pop star has always been vocal about her life but this film goes much deeper into her lifelong journey.

The documentary is a mix of a sit-down interview and behind-the-scenes footage, with Lovato detailing various topics on her life like drug abuse, suicide, her relationship with Wilmer Valderrama, mental health, family problems and more. “I was 18 when I first when into treatment. When I first got diagnosed with bipolar disorder it just made sense. When I was younger I didn’t know why I would stay up so late writing and playing music," Lovato says. "And then I learned about episodes of mania, and I realized that that’s probably what it was—I was manic. In a way, I knew that it wasn’t my fault anymore—something was actually off with me.”

She also attributes her love for music for helping her get through: “When I look back at my life, I fell like if I didn’t have music, I don’t know what I would have. I have my friends and my family, but music gave me a purpose when I was bullied in school, it gave me the motivation to keep going and prove to everyone that didn’t believe in me that I was going to be something someday.”

Tell Me You Love Me, Lovato's sixth studio album, arrived on Sept. 23 and features songs like "Sorry Not Sorry" and "You Don't Do It For Me Anymore." It is the follow-up to 2015's Confident.
