Demi Lovato, the 18-year-old star who sought treatment for what her reps called "emotional and physical issues" last fall, opens up about her struggles with food addiction and "cutting" in an interview with ABC News.
In Lovato's first television interview since her three-month stint in treatment, Lovato tells ABC News' Robin Roberts about the depression that has plagued her since childhood and how she plans to get her life back on track.

The actress and singer-songwriter became a teen idol after her starring role in the "Camp Rock" movies on the Disney Channel. She released her debut solo album in 2008 and headlined her first international concert tour in 2010. She stunned fans and the entertainment community when she cut short her tour with the Jonas Brothers to enter treatment in November 2010.
"Demi has decided to take personal responsibility for her actions and seek help," her team said in a statement at the time. "She is doing just that. Demi and her family ask that the media please respect their privacy during this difficult time. She regrets not being able to finish her tour but is looking forward to getting back to work in the near future."
Demi Lovato Has History of Being Bullied
Lovato, who has a history of being bullied, told Roberts in an interview last year that the verbal abuse from other middle school students was so bad that she chose to be home-schooled. The teen sensation has since become a supporter of anti-bullying efforts.
"Bullying prevention is my main platform," she said in a previous interview. "You know, anything I can do to make people aware so it can stop, I'm all for it."
