Demi Lovato talks about eating disorder

Singer Demi Lovato has opened up about her recent treatment for an eating disorder and cutting, saying she hopes to help other sufferers.

"There is a certain point where you learn it's taking a toll on your entire family, and your career and everything in your life and it's jeopardizing so much that you have to get help," said Lovato, 19, who admitted to "Access Hollywood" Wednesday that she was making herself vomit over five times a day.

"The breaking point for me was, I was just tired, I was out of the country and I was away from my family, things had just built up to a point. When you're putting on concerts and you're not eating, you know, that will take a toll on you. . . . I snapped and I regret it to this day," she said of abruptly exiting the Jonas Brothers tour last year.

"Treatment was the best decision that I ever made and it saved my life," she said, adding, "I feel a lot better and I feel like now that I'm able to speak about it -- I'm able to help younger girls with their issues they're dealing with and that makes me feel like a role model."
