After pondering a bit, I decided that although my fatigue might be aggravated depression, it is very unlikely that it would also cause swollen eyes or fever. So, at last, I went to my doc friend, who got a bucket of blood drawn to test for any random bug that may cause not very specific symptoms.
The tests got back and I was sorta positive for a few bugs. Today, I finally read through part of the mail backlog and found an invitation to experiment on humans - a bunch of researchers at the university is testing students for toxoplasmosis and doing various psychologic tests to find out how toxo correlates with cognitive function. And, I possibly have toxo. If it gets confirmed, I'm going to be put on antiprotozoans (or whatever the anti-toxo meds are) because my doc decided just to bomb the bugs and see what happens because tests or not, I'm miserable enough. I mailed the researcher back with this, maybe I'll enter the literature as a nice case study of cognitive whatever while being treated.
Meantime, I feel crappy.
