Demi Lovato has talked about her recent stint in rehab, revealing a long-term battle with an eating disorder.
In an interview with Seventeen magazine in the States, the Disney star said: "I will deal with it for the rest of my life because it's a life-long disease. I don't think there's going to be a day when I don't think about food or my body, but I'm living with it."
The 18-year-old went into a clinic for treatment in November last year because she wanted to "take control" she said, adding that she is now doing better.
She offered some advice to fans: "I wish I could tell every young girl with an eating disorder, or who has harmed herself in any way, that she's worthy of life and that her life has meaning. You can overcome and get through anything."
The Camp Rock and Sonny With A Chance star added: "If you are going through that dark period, go to your family and closest friends. Don't put yourself in danger. It's very crucial that you get your feelings out - but don't ever inflict harm on your own body because your body is so sacred.
"I don't let anyone's insecurities, emotions, or opinions bother me. I know that if I am happy, that's all that matters to me."
