The imagery is, as always, wonderful. This “emo flu” business is odd and a little alarming… I’ve certainly heard of, and experienced, illnesses affecting emotional state, but a semi-consistent version suggests a possible new development. As if we didn’t have enough crises on the table!
Of course, any effect to the brain/nervous system would be modulated by what’s already there… from your comments above and the general tenor of your blog, you may be a “well-compensated depressive”, which would certainly represent “something different” for the virus to affect. I’ve several times had a remission from my own depression, while affected by severe illness. (Thinking about it, most of those illnesses were presumptively viral.)
