Get better soon!

If that mental 'fog' doesn't lift, there's been some interesting work relieving probably-similar 'fog' that comes from chemo treatments. They've had some success with methylene blue and trans-cranial near-IR. About the only easy action item that might come out of that is to be sure you get plenty of sun exposure. Wearing sunscreen doesn't make it not help - so do that.

Also, as a guy, I have to say my immune system sucks compared to a lot of people, including my wife - so it might not be malingering; we're just not good at this not-getting-sick thing.
