Fibro or flu?

Extra sick. I am so extra sick and have been so for over a week.  The fact that I have severe fibro leaves me with an awful lot of daily challenges to overcome and/or adapt to. 
However, this is flu season and I may have a flu on top of the fibro.  I suspect this because of the shortness of breath, stomach pain & diarrhea, constant headache, and debilitating fatigue, steady for over a week and last night I actually heard a bit of wheezing in there, so, I suspect a flu.  It is really difficult to differentiate sometimes.
If anyone wants to know what it is like to live with severe fibro, ask them how they feel when they have a flu and how they would feel if this flu thing never went away. 
Well, off to bed again shortly to read and rest until this thing eases up.  I am thankful that I have a safe, quiet place to go to get the rest I need.
