Hey could you help me im really nervous!!?

so my whole cl did this project on the holocaust and its call the footstep project and we had to make a poster on a victim a persecutor a rescuer or a bystander and i picked out victim so i decided to do Elie Wiesel because i wanted to learn about him.so i made my poster and it looks really nice but the thing is we have to present in front of the whole cl :O and i get so nervous. some people already went yesterday and one person went today but luckily it was just the persecutors and i think i have to present tomorrow and i pretty much know enough to present but i am SO nervous even if i practice by myself i forget what to say!! helppp meeee :o
