Can't breath through my nose...

I am sick... miserably sick. I can't breath through my nose, and my ears are plugged, and my throat is scratchy, I am achy all over and I sound like a baby sea lion when I cough... yuck. This is the first time I have been legitimately "down-for-the-count" sick in a while... but can I stay home and milk it? NO!! I tried calling around last night when I started to feel unhealthy, to see if someone was available to at least take this morning's class (I am supposed to work today 8:30am - 11pm) but absolutely no one who would be able to teach this particular class is available. So I must soldier on and try to at least get through this morning - pray someone can take my afternoon class... I do already have someone lined up to take my evening class. This stinks.
