Please tell me if this is normal

My english teacher said some pretty mean things and accused me of lying when I said no i wasn't sleeping, and i showed her the proposal writing she was dictating outloud. Ig she got defensive or smth and told me off infront of about 50 students and then went on to talk about how,these days, students just say no or wtv when teachers are standing and keeping an eye on all of them.....

While listening to all this, my hands suddenly started to shake and I had trouble breathing cuz my stomach would just not relax no matter how many calming breaths i took. At last, i made an excuse of feeling pukish and ran out of the class where i hyperventilated and could not stop the tears. A few minutes later, I went back in but I still could not calm down, for the love of god.

She took one look at me and my friend who was patting my arm and telling me to stop crying and sent me out of the class and said take deep breaths outside.

I went out and still couldn't stop the tears or the hyperventilation, this went on for about 30 mins when the period finally ended and we had a lunch break.

My friends calmed me down and I just nodded along until break was over

Is this normal?
