Hi neighbor!
If misery loves company, I'm right there with you, now in day four of the misery. Though without your other health problems, I'm managing to avoid doctors visits so far.
I'm pretty sure I caught it from my three year old. He had fever for five days, and bad coughing for close to two weeks, but his doc never found anything treatable.
Hang in there, and I second the suggestion of chicken soup - home made if possible. I just had a bowl and it made me fell much better!
