And then it occurred to me that fatigue and brain fog were also symptoms of Lyme disease. Which a blood test just confirmed I have. I've probably had it for months.
Rejoice! For there is nothing like a diagnosis that can be acted on.
So now I take a bunch of antibiotics (and carry around an Epi-Pen, and after this morning's little incident get way more vigilant about keeping the kids away from the damn Epi-Pen), and with any luck, I'll get my nervous system fully online again. It's such a lovely nervous system. Comes in handy for writing with, you know.
