Not sure what to do...

Ok...  As of last night I had a very determined resolve to have a better outlook on life and all that.  And it would have stuck around had Beth not gotten sick on me.  Normally, Beth being sick is not a big deal, but this isn't just normal cold or cough junk.  This is the PUKIES.  Nothing panics me like someone puking, especially if I need to deal with it.  I'm Mommy, super hero and general make-me-feel-better person.  I CAN'T STAND IT.  Not the consoling my kid part, the actual body fluids part.  So right now, I haven't slept all night and Pete just left for work.  I'm shaking and crying and so overcome with panic that I'm not thinking clearly.  I don't know what to do.  I have three kids that need their mom today and all I want to do is check out (and take a nap).  Help!
