After months of being quiet, Amanda Bynes has made it back to the headlines with her DUI arrest last Sunday. Besides the arrest, Bynes has reportedly been engaging in erratic behavior, ditching classes at fashion school as well as taking Adderall and smoking weed.

Bynes was released from her court-ordered parental conservatorship in June and allegedly started missing classes at the Fashion Institute of Design and Merchandising in Southern California, where she had been enrolled. A source told RadarOnline that Bynes’s instructors tried to reach her but got no response, so she consequently flunked out of the school. The source also said that Bynes has stopped taking her psychiatric medication and resorted to drinking alcohol and smoking pot.

While Bynes was still living with her parents, other sources claim that she had already been behaving strangely. A source told People that the actress’ behavior at the Thousand Oaks gym she had been going to over the summer showed how she was not “100 percent well.”

“She is still obsessed with her body and spends more time in front of the mirror than she actually works out. She doesn’t like when people look at her and has even confronted a few other members,” said the source. Her parents also reportedly monitored her closely during activities such as driving, and the source said that Bynes would sometimes argue with her father in the car.

Bynes reportedly made bail after her arrest on Sunday, but according to New York Daily News, her parents have not seen her since she left their watch. “We know nothing about this. We were called by the press. I’m getting calls all day long. That’s all I know,” Rick Bynes told camera crew of X17 at his home. “She’s 28, she does what she wants. We don’t know a thing.”

The social media accounts of Bynes have been relatively quiet since May, when she last posted a picture of her and her sister looking happy and healthy.
