I am beginning to think there actually might be a zombie pathogen going around.
Some virulent form of strep or maybe a virus that's lowering our bacterial immunity.
All the susceptible people I know are suffering from runny noses and high anxiety this winter. Friends having breakdowns. I personally am having panic attacks and ruminating.
It's an impossible hypothesis to test at this point. And I know it sounds grandiose and self serving. But if you have been feeling agitated and dark, I recommend doing some basic immune system management.
