I am SO very sorry that this vile situation has afflicted you. Yep, I TOO, can fully relate to the dizziness, loss of being an active, healthy, 'high-functioning' individual. Fatigue is NOW my constant BFF.
Weakness, thirst, brain-fog, etc. etc., are among a plethora of afflictions attributable more than simply Covid.. Yes, have had it three times, BUT, these L.C. issues arose after having had the Moderna vacs, twice. Color me cynical, but, I believe Big Pharma, poor testing trials, and remanent vac proteins are also, possible culprits. Covid is a, 'gain-of-function' creation designed to resist any cure. Current science, (vacs), can't compete with it.
