Amanda Bynes Graduates From FIDM Fashion School in Los Angeles

Amanda Bynes has graduated from FIDM fashion school in Los Angeles.

The former Nickelodeon star shared a photo of herself Monday in a cap and gown next to a fellow graduating pal, captioning the post ... "FIDM graduate 2019 #fidmgraduation." Amanda's got her hair pretty long right now, and it's dyed blonde and pink. 

The 12,000-student ceremony went down Monday night at Staples Center in L.A., where Amanda walked across the stage with an Associate's degree in fashion design. Eyewitnesses tell us Amanda seemed ecstatic -- she was getting tons of love from her teachers and peers.

The happy news comes months after Amanda rechecked herself into a facility in January. As we first told you ... her going back for treatment was a result of a backslide from being back in the spotlight after her Paper magazine cover story.

Amanda opened up a lot in the feature, revealing that starring role in 2006's "She's the Man" sent her into a spiral of depression. She also blamed a lot of her issues on drug use. At the time of the article -- November 2018 -- Amanda said she was 4 years sober.

Amanda was diagnosed with bipolar disorder, and has been under a conservatorship for the past 5 years, but the problems began several years earlier.

Amanda's been enrolled since 2014, and has been attending on-and-off. She took a break last year to get back into acting, but returned to complete the classes.
