Amanda Bynes' bizarre behavior: A timeline

The post comes days after Bynes tweeted that she has been diagnosed as bipolar and manic depressive. Since being released from a psychiatric hospital on Oct. 30, the former child actress also made several negative statements about her appearance on social media. "My hair is hideous," she wrote in one, and "I look awful" in another.

Bynes also claims her parents have been withholding her belongings and money from her. "So until I get a different conservator ill look terrible because I don't have enough to get new clothes or anything I need," she posted Tuesday.

Bynes' mother, Lynn, was reinstated as her conservator on Oct. 22.
