Teen starlet Demi Lovato is leaving her hit Disney Channel show, 'Sonny with a Chance,' to focus on her music career. "I don't think going back to 'Sonny' would be healthy for my recovery," Lovato tells PEOPLE. "Being in front of a camera would make me nervous."

Late last year, Lovato entered a rehabilitation facility for "physical and emotional issues" related to an eating disorder. When the 18-year-old singer-actress entered treatment, 'Sonny With a Chance' was placed on hiatus. Lovato was on tour with the Jonas Brothers when she decided to get help and was forced to withdraw from the tour.

"We respect Demi's decision to focus full time on her music and not immediately return to her acting career," the Disney Channel said in a statement. "She is a talented young woman, and our hearts are with her as she continues to take action to improve her health and bounce back from adversity."
