We're happy to see she's on the mend!

Mischa Barton grabbed dinner with pals at Hollywood hot spot Catch over the weekend, and she told us she's "doing good" after her recent hospitalization for erratic behavior.

Fans were concerned the actress had had another breakdown when video surfaced of her hanging over her neighbors gate and screaming nonsense, but she explained that she had actually been slipped the date rape drug GHB.

“On the evening of the 25th, I went out with a group of friends to celebrate my birthday. While having drinks, I realized that something was not right as my behavior was becoming erratic and continued to intensify over the next several hours,” she told People.

"I voluntarily went to get professional help, and I was informed by their staff that I had been given GHB. After an overnight stay, I am home and doing well. I would like to extend a big thanks of gratitude to the professionals at Cedars-Sinai for their great care and professionalism. This is a lesson to all young women out there, be aware of your surroundings," she added.

Bruised ego aside, she seems happy and healthy!
