Friends of The O.C. star Mischa Barton insists that she has been on a destructive path for a while now.
"She has been on a destructive path for a while now," People magazine quoted a friend as saying. "Her drug and alcohol [use] has gotten to a point where it drove people away," the friend added.
According to the sources, Barton has been "dealing with a lot of personal issues?.
"I don''t think she knows her limits," adds the pal.
Currently, the 23-year-old actress has been put under involuntary psychiatric evaluation at Cedars-Sinai Medical Centre in Los Angeles.
Barton has battled demons before. In July 2008, she told Marie Claire magazine that she'd sought treatment for her problems.
Experts say Barton could be discharged by Saturday afternoon if she demands to be released or doctors find her to be stable.
