demipurple230.jpgDemi Lovato, star of Disney's Camp Rock, is seeking treatment due to a history of emotional and physical issues, including struggles with an eating disorder and cutting.

The 18-year-old actress was also reportedly bullied in school, and a source tells People, the trauma has remained with her for years. The source adds, "Demi is taking control by getting help."

Lovato, who was currently touring with the Jonas Brothers on the Camp Rock Tour, has also shut down her Twitter page.

As a spokesperson for teensagainstbullying.org, Lovato recently wrote the following letter to bullied kids:

    "I actually used all of the bullying as a motivation to succeed. I think I have actually become a stronger person because of it. But I know that many kids and teens do not have all of the support and outlets I have, and that's why I want to do something about bullying. I want to make it stop."


In a statement released to X17online, Lovato's rep said, "Demi has decided to take personal responsibility for her actions and seek help."

Several years ago at Miley Cyrus' 16th birthday party, Demi was photographed with cuts on her left wrist ... which led to speculation that she was a cutter. At the time, her rep said, "Demi Lovato isn't a cutter."

Earlier this year, Lovato, who split from Joe Jonas in March, portrayed a schizophrenic in a guest-starring role on ABC's Grey's Anatomy.
