(Cover) - EN Showbiz - Demi Lovato has done things in her life that she is not proud of and that she "regrets".

The 18-year-old Disney actress is on the road to recovery after leaving rehab back in January for "emotional and physical issues".

But in a new interview with radio host Ryan Seacrest, Demi explained she still has a long way to go.

"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 revealed.

"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."

Demi was in a treatment centre in Illinois for nearly three months and later admitted she had an eating disorder and had cut herself.

"My family's known that I've had issues with food and eating for about six years now," Demi admitted.

"I was able to check in with them but it got to a point where I just was lying... about eating and about being happy. There's a lot of pressure these days. I feel like I live in a city where no woman eats!"

Although she said she was never suicidal, Demi admitted to going through "some really, really dark times".

Demi has a new single out called Skyscraper which she recorded at the height of her emotional battle just before she entered rehab. (C) Cover Media
