Remember when I mentioned that I was tired and my back hurt all the time? As it turns out, I had Lyme disease! I was sick! I finally got a fever that lasted a few days, a stiff neck and headache, and a classic rash.
Moral of the story? I'm apparently not just a whiner, and childrearing isn't always to blame if you think you aren't going to make it through the rest of the day.
