I'm so nervous, sorry to bother you guys with this.

Hi everyone :)
I'm really sorry to bother you with this again but as some of you know I'm doing a singing festival/competition on March 3rd and some days ago I had a sore throat from practicing (much better thanks to everyones advice). I know I have to do this because I can't back out and I won't get my money back and I'm really excited to tell the truth but by nerves are getting to me so much! Everyday at school I have to go to the bathroom because I feel so sick! I'm getting headaches everytime I think about it, literally. I feel as if I'm going to pass out. I'm not overreacting that is how bad my nerves are. Does anyone know how I can handle these nerves... I only have until Saturday and I am so scared I cannot explain. Please help me, thank you everyone :)
