"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," her rep said.
The rep didn't specify the nature of Lovato's problems. But a source close to Lovato's family said, "She was bullied in school. She fought through eating disorders and has struggled with cutting. Demi is taking control by getting help."
