Demi Lovato: ?I?m glad I hit rock bottom when I did?

In a candid interview about her battles with bipolar disorder, depression and bulimia, the 19-year-old Disney star tells Latina Magazine that although she now feels “happy, healthy and driven', life still gets her down sometimes.

She says: “I continue to have moments. I still think sometimes that I’m not strong enough and I need extra help. It’s a daily battle.

'Things can still get me down sometimes – but nothing keeps me down.”

The Sonny With A Chance star admits she feared that her career was over after she punched a back-up dancer last November while on tour with The Jonas Brothers and was admitted to rehab for “emotional and physical issues”.

“I thought I was going to lose everything when I checked myself into treatment,' she says.

'I didn’t know if I would have a career at all when I came home.

'So it really hit me – I hadn’t been grateful. In that sense, I can honestly say I’m glad I hit rock bottom when I did.

'Most people don’t have those moments. I see a lot of young people in this industry who feel entitled because they haven’t hit rock bottom yet.”

She adds: 'I feel blessed when I get an opportunity now.”
