"It's hard to imagine that a young girl who started out on ""Barney and Friends"" and the Disney Channel would end up in a treatment center for eating disorders and self-mutilation. But that's what happened to Demi Lovato. In January, the actress and singer, then 18, completed her stay at a facility near Chicago, leaving with a clearer head and a diagnosis of bipolar disorder. ""I feel like I am in control now where my whole life I wasn't,"" Lovato told People after her stay. Lovato's announcement came less than a week after it was revealed that Catherine Zeta-Jones was seeking treatment for bipolar II disorder."
