KCee The thing that concerns me a little is, what kind of things make a person suddenly feel low energy? And do they fit in this situation?
Mood. No.
Certain drugs. No.
Lack of sleep. No.
Illness. Yes but it seems to be otherwise gone, so what can it be doing to kill energy?
Immune system working hard when it no longer has to? Possible.
Heart problem? Unfortunately, that's also possible.
Both the disease and the vax have been somewhat associated with effects on the heart. I hope we haven't suffered a bit of heart trauma here.
