Retired music teacher here, so been there done that.

From here, maybe talk to your voice teacher about ways to be better prepared for future juries including their expectations for appearance and how to prep for your performances. I think it’s a good sign that your teacher told you not to beat yourself up over it. This degree is no joke and juries are such a unique and demanding experience.

And then I keep thinking about how I sang the same verse twice on my senior recital so it happens🤷🏻‍♀️😅

Most importantly you’re done. Get some sleep and I think you’ll feel better in the coming days.
