Should I go to school today?

Okay, My throat feels as if it's on fire, I'm congested, and I feel as if I'm going to throw up. But the problem is, I'm cheer co-captain at school, we have to cheer at a outdoors football game. You can imagine our outfits, Today's high is around 40. So If I go, I will get even sicker then I am now. And I also have to run the mile in PE, which is outside. Should I go to school?
