No OP but similar situation. It's easy to make the difference: I've been in terribly stressfull situations before. I went to live in Mali, started business, got Malaria, lost everything to the war and had to start all over, going back to my country.

It's not the same. Covid got me bad.

But strangely, only after the third dose of vaccine. Right after it in fact, and ever since.

But it's possible we will learn we are coupounding effects on a lot of fronts: stress from the situation, covid itself, unexpected side effects from the vaccine, and maybe something else.

Hard to tell.

But yeah, this is not regular run of off the mill, stress response.
