Anxiety

I get really bad anxiety at school and last week I had a ton of anxiety attacks during my classes because it’s a new year and teachers keep asking me questions. My hands continue to shake, my heart beats way too fast, can’t breathe properly and tear up just thinking about being singled out or called upon. I take no medication and all I can do is take deep breaths and laugh at myself (don’t work that well) sometimes I think the teachers just think I’m shy. Do you think it would be better if I emailed the teacher about my anxiety??
