(CBS) - Demi Lovato is talking about her decision to seek treatment last year, saying she sought medical help for her issues with cutting, anorexia and bulimia after having a "breakdown."

"I did some things I that I regret to this day," the 18-year-old former Disney star told Ryan Seacrest on E! News. "There was a bunch leading up to it - emotionally and physically - that I was doing to myself that I realized was unhealthy for my life."

"I wasn't going to continue to be alive if I continued to treat my body the way I was," Lovato adds.

Last October, Lovato dropped out of her world tour with the Jonas Brothers to enter a treatment facility for "emotional and physical issues."

The former " Sonny With a Chance" star tells Seacrest that she battled with depression since she was 7, and was diagnosed as bipolar when she went into treatment.

"I was unmedicated for so many years and it led to so many problems, which eventually led me to some of my biggest problems: Anorexia, bulimia and cutting."

Today, she says it's a "daily journey" to stay on track and admits that staying healthy will "be a struggle that I'll have to deal with for the rest of my life."

"I'm not going to be perfect, but if I can make it through the day, that's all that matters," she says.

As for why she decided to talk about her struggles, Lovato tells Seacrest "if I can help somebody by telling my story, I'm going to do it 100%."
