Demi Lovato is opening up about her battle with alcohol and drugs, her eating disorder, self-mutilation and her volatile friendship with fellow Disney alum Miley Cyrus.
"Miley and I are strong headed. When we fight it's brutal and we're like, 'We're never going to be friends again!' Then two days later, were like, 'I love you and I miss you!'" The nineteen-year-old tells the new issue of Seventeen magazine.
One of the two friends' "brutal" fights went public in 2008 after Miley posted a YouTube video mocking Lovato and Selena Gomez.
Then, in 2009 they got into a Twitter feud following a snippy remark Lovato made after Miley posted a photo of the two of them together, with the comment: "Now this is what true friendship looks like. None of that hollywood c***. @ddlovato I miss you :)"
"Yeah... It's just kind of hard to miss somebody that I don't know anymore." Demi shot back.
However, Lovato insists that Miley and she will always be friends, through thick and thin. "Both Miley and Selena will never leave my life no matter what happens, because we've been through so much together," she tells Seventeen.
"Demi has decided to take personal responsibility for her actions and seek help," her rep said in a statement, "She is doing just that."
"Demi regrets not being able to finish her tour, but is looking forward to getting back to work in the near future."
She spoke about her issues with Ryan Seacrest on his KIIS FM breakfast show. "I just had so much growing up to do...I just had so much going on in my head. I ended up doing things that I regret to this day," Demi said."It was the elephant in the room. It was affecting every aspect of my life. I was cranky, I was irritable, I was not pleasant really to work with."
She goes a step further with Seventeen though. "I'm not gonna lie. I was self-medicating," she says. "I was doing things like drinking and using drugs, like a lot of teens do to numb their pain. But now I don't drink, I don't do drugs, I don't throw up after my meals, I don't starve myself. There's nothing that I do that I feel ashamed of."
