Demi Lovato had to learn that she was "worth recovery".

The 19-year-old singer - who was admitted to a treatment facility for three months in November 2010 to receive help for an eating disorder and self-harming - explained while she is aware her troubles will always be a part of her life, she now likes to "celebrate" overcoming her demons.

Speaking on upcoming MTV special, 'Demi Lovato: Stay Strong', she said: "One of the hardest things was learning I was worth recovery. And I'm allowed to celebrate it, which is a great feeling.

"Recovery doesn't have a day off."

Demi has previously admitted her mother Diana is her "anchor", and has made her feel positive about her future once again.

She said: "My mother is everything to me. She's my anchor, she's the person I go to when I need to talk to someone. She is an amazing woman. I got through it with the support of people like my mother.

"You can only make it when you feel that you are loved, no matter what, when you feel that you will get another chance. I am grateful and I am ready to make this year a much better year. I feel great."
