Warning: this post discusses brain fog as a symptom of Depression/Anxiety
Disclaimer time: I am not any kind of medical, psychological, or neurological professional. I'm a chick with a blog and some personal experiences - nothing more, nothing less.
Some days, my brain does not work.
Call it brain fog, call it fuzziness, call it extreme mental fatigue.
It's common with migraines (which I get,) and Depression and Anxiety (which I have,) as well as a whole bunch of other conditions - including Long Covid, for which it's gotten a lot of media attention.
