Might be rejected from music school for having a reserved personality

It’s pretty much the title. I’m a high school senior and auditioned at my local state school. It’s no Juilliard or Curtis but they have a good music ed program and it was pretty much my dream school. The flute professor (I play flute) offered to meet with me after my audition if I had any questions and I accepted. She told me she wasn’t sure if she would accept me or not, but not because of my playing. She said that my playing was good, said she liked the way I had adapted when she asked me to try something different, and that she thought I would thrive at the school. But she thought that I had a reserved personality and that was the reason she was considering rejecting me. It’s true that I’m more of an introvert, but I don’t feel that it was a fair judgment when this was our second time meeting, and after a nerve wracking audition. She told me that she couldn’t see my love for music and that she thought music ed majors had to be especially expressive otherwise they wouldn’t be able to teach people what music is. Expression was always my weakest part in playing music, but my teacher thought I had improved a lot and that I was ready. She was just as surprised by a personality judgment being the reason I might not get in. I feel really demoralized now and I don’t know what I’ll do if I’m actually rejected. I guess I’m just looking for advice. Did anyone here experience anything similar? Would you agree that a less loud personality has a negative impact on one’s ability to teach?
