After a troubled year that included bizarre Twitter rants, erratic behavior and multiple DUIs, Amanda Bynes seems to be doing well since her December 2013 release from a four-month stay at a psychiatric ward.

The former Nickelodeon actress, who just yesterday accepted a plea deal in a DUI case, is feeling remorseful about her past behavior, TMZ reports. Sources tell the site that the star feels particularly embarrassed over a graphic tweet she wrote about Drake, which you can read below:

Bynes, who hasn't tweeted since July 2013, is also reportedly moving on in her life. According to TMZ, she is no longer smoking pot (Bynes was involved in a bong-throwing incident in 2013, but the case was dismissed) and is in the process of removing a number of "inappropriate" tattoos. But most importantly, the 27-year-old star is continuing her education, taking classes at the Fashion Institute of Design Merchandising in Orange County, Calif.

We couldn't be happier for the 'Easy A' actress, who has reportedly been diagnosed with bipolar disorder and schizophrenia. She seems to be getting her life under control and appears to be acting like her old self. We wish her the best in her recovery.
