i have been so sick

Is this just the flu?  Fever, unbreakable, at a brain-boiling 101 for 48 hours.  I took toxic amounts of alternating Tylenol and Advil, with tons of GatorAde and ice water, but could not break it.  All day Saturday and Sunday, just burning up.  I was seriously tempted to start making funeral arrangements.  And cough, so bad that now my rib muscles are ripped, hurts every time I cough or sneeze.  Body aches, everything hurts, head, shoulders, knees, elbows, back, hips.  I am dying.  So now, day four, productive cough and head congestion, finally no fever, but still muscle aches and headache.  I can hear my lungs rattling with gunk, so I've now started the Mucinex.  Of course, no health insurance and just trying to tough this out on my own, but surely hating it.  My little one had it, too, but not to the degree that I am sick.  23 percent of his school is out sick.  Anyone else?
