I have done many presentations before and have always been nervous, but not like this. I dreamt about it and I wake up sweaty. Every time I think about it, I feel like crying. When I practiced the presentation in front of my mom and sister, I also felt like crying and went lightheaded. I am also sick today, but i don't have a fever. Should I talk to the teacher if I can just present in front of her and not the whole class(35 students)?
