"Demi has decided to take personal responsibility for her actions and seek help. She is doing just that," the rep adds. "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."
The rep does not detail further about Demi's issues but it is said that the 18-year-old star is not seeking help for drug use. Instead, the singer/actress is reportedly dealing with eating disorders. "She was bullied in school. She fought through eating disorders and has struggled with cutting. ...Demi is taking control by getting help," a source close to the family tells People.
Another source tells TMZ that the former lover of Joe Jonas was in a physical altercation with a female member of her tour recently which was a "catalyst" in her decision to seek professional help. Meanwhile, E! News learns that her exhausting work schedule "overwhelmed" and ultimately took its toll on her.
