Mischa Barton insists she hasn’t lost her marbles. The actress — who was recently released from hospital after being placed under involuntary psychiatric hold — says people think she’s “unstable” following the incident. “I’m getting sick of answering questions about it,” Mischa moaned. “I just had a bad time of year and now it’s all over and done with, and I’m just very happy to be feeling happy again and back on top of it and not so worried about everything. “It was just too much to handle for me at the time. “One stay in the hospital was turned into this huge ‘She’s lost her marbles!’ thing, and people look at me like I’m unstable and they should probably cross the street when they see me.”
