i think i know whats the problem
what's that

sleeping few hours kills the body
from there you get heart problems and kidney problems as well
i would definitely at this point reserve an appointment with a doctor for overall checkup on vitamins/physical health/mental health to see whats going on
and not leave it cause it may get worse you never know
most important thing is breathing fresh air
Maybe it's long covid

you got a headache? must be covid
With that new varient and all, people get paranoid
but maybe less now, after all of big Boris' parties during lockdown being leaked
