I Want Drake To Murder My 'Vagina' Comment Horrifies Amanda Bynes

Amanda Bynes has turned a new leaf ... and one of the signs is that she is now remorseful about things she did and said when she was at her worst -- particularly her comment about Drake, "I want Drake to murder my vagina."

Sources directly connected with Amanda tell TMZ ... she is in the territory of being her old self again.  They say the fact that the Drake comment "horrifies her" shows she again has a sense of the difference between right and wrong.

But there's more.  We're told Amanda has stopped smoking weed, she's in the process of removing a number of inappropriate tattoos, and she's kind to people with whom she interacts.

Most impressive ... Amanda is now at FIDM -- the Fashion Institute of Design Merchandising in Orange County -- and she's become so self-confident she makes presentations to her entire class and freely interacts with her classmates.
