Mischa Barton “probably” wouldn’t star in “The O.C.” again.

“It’s something I came so close to not doing,” Barton, 28, told Metro UK in an interview published Tuesday. “I had a really great thing with film. People say be grateful for what you have but [it’s] certainly not the kind of thing I was expecting it to be … I’ve kind of seen it all.”

After her sudden rise to fame, Barton suffered a number of public downfalls. She was arrested for driving under the influence in December 2007 and involuntarily admitted into a psych ward in 2009 after she threatened to kill herself. As of Monday, she’s $100,000 behind in mortgage payments on her Beverly Hills home.

Although she suggests up-and-coming stars keep their personal lives private, Barton says she also found it difficult to remain calm during turbulent times in her life.

“There’s tough balance in being a nice person about it and becoming too closed off and not nice,” she said.
