Amanda Bynes Amanda Bynes

Amanda Bynes was released from a psychiatric hospital Thursday and wasted no time getting back to one of her favorite hobbies: Twitter.

The actress, 28, posted a series of erratic messages on Friday in which she called her family's lawyer "corrupt," her celebrity manager Sam Lutfi "ugly" in addition to writing several nonsensical items like "I am ug butt."

However, Bynes also used social media to defend herself and her state of mind to her followers. "I am going to court today with my lawyer to prove that I am more than capable of handling my personal life and finances and I am enraged," she wrote. Bynes' recent communications come after TMZ.com reports she was spotted roaming the Sunset Strip Thursday night and allegedly was seen talking to herself inside a restaurant.

Bynes went on to reiterate previous claims about sexual abuse she suffered from her father, whom on Friday she accused of being a "sexual predator" who "should be in jail." She first made the allegations several weeks ago, and then blamed the allegations on a microchip implanted in her brain.

She subsequently entered a psychiatric facility on Oct. 10 after Lutfi and her parents flew her to Los Angeles under false pretenses. She was brought to a hospital and put on a 72-hour psychiatric hold. That was extended to a 14-day hold on Oct. 13, and then for a month on Oct. 27. However, she was released following a hearing on Thursday. Her mother was reinstated as her conservator on Oct. 22.
