Sick of Being Sick

I don't often get sick.  Really I don't.  This winter has been a killer for me.  In November I ended up with strep throat.  Over Christmas and into the new year I had that great flu with the congestion and cough.  A cough always lasts a long time for me but I was finally over it.  Today I went in to the clinic and was told I have bronchitis.  At least it isn't pneumonia.  I'm so tired of coughing.  My back muscles hurt from coughing.  I'm sick of being sick.  I'm hoping this isn't a sign of turning 50!
