The documentary, which Lovato directed, also featured a conversation between the actress and Barrymore about when they were first introduced to drugs. Barrymore claimed to be 10 years old.

At one point, someone asked Lovato if she had the choice to do it all over again, would it be worth it?

"There definitely is not a manual on how to navigate this industry at such a young age," Lovato said in the trailer. "I wouldn’t end up where I am had I not made all the choices leading up to this point. But it came at a price."

Lovato appeared in 15 episodes before "Camp Rock" would shoot her to stardom in 2008.

In 2010, Lovato filmed "Princess Protection Program" with Selena Gomez before filming "Camp Rock 2." Things began to fall apart on the "Camp Rock 2" tour. Lovato was 17 at that time and was drinking alcohol and doing drugs, namely Adderall, according to her YouTube documentary, "Simply Complicated." Lovato punched a backup dancer who revealed the actress's drug use, leading her to check into rehab.

"I think I’d passed the threshold of what I could withstand emotionally and physically," she told The Hollywood Reporter. "And I didn’t realize that child stardom could be traumatic. And it isn’t traumatic for everyone, but, for me, it was.

"At Disney, you became this instant role model, whether you liked it or not," Lovato explained. "And because Disney Channel was so big at the time, there was also this unspoken pressure that if you did make a mistake, you knew that there were millions of people just waiting to take your spot."

Lovato's documentary premieres on Hulu Sept. 17.
