Ugggh, should I go to school tomorrow?

I have really bad headaches, congested nose, bad cough, and aches & pains. The headache is probably a contribution from being sick last week and falling in the shower over the weekend and banging my head. I have only missed like 8 days this year. The thing is I don't want to miss my trig review for the test, but it doesn't really matter because I can't think straight. I would also be missing volleyball practice, but that isn't too big of a deal because the coach knows I have been sick.
