Choir solo... PRACTICE GONE WRONG

So it’s contest season for chamber choir, and I’ve been bullied all year by a senior who’s name won’t be said as they may use this app. Well here I was introducing myself and then started singing my first solo piece “the lass from the low countree” in the middle of the song I made eye contact with said person and I walked out. I’ve never had problems sing in front of audiences but the minute I made eye contact with HER in particular I broke down. I’ve been bullied to the point now I have anxiety attacks just thinking of going to choir.
