Former 'O.C.' actress Mischa Barton has angered her close friends by partying at the All Points West music festival in New York even though she was just placed under involuntary psychiatric hold at Los Angeles' Cedars-Sinai Medical Center.
"It's scary to see her out right after she's received treatment," family friend Eric Ziegenbein told Heat magazine. "When I found out she'd been partying again, I was shocked. I thought she would chill out for a bit. The fact she was out right away proves she's not taking things seriously enough. It was like a big 'f**k you.' She's too proud and independent sometimes."
The 23-year-old starlet was under a 5150 hold for two weeks - which allows people to be forcibly held if they are deemed dangerous to themselves or others, are gravely disabled or have a mental disorder - after friends became concerned she was suicidal.
Some have said that the actress' drink and drug use was affecting her career and personal life. Another friend, Suzanne Coppin, is frustrated Mischa is trying to deal with the problems on her own without listening to loved ones.
"She has a support group, but it's obvious she's ignoring them," Suzanne said. "I'm disappointed she's not taking advice and is still doing her own thing."
This is not the first time Mischa's friends have voiced concerns about her well being. Earlier this month, many of them expressed their fears that she had returned to work on her new TV series 'The Beautiful Life' too soon after being released from the hospital.
"There still are issues," one friend said. "Mischa's just not herself at all. I think she's gone back to work too soon."
