While Scott's symptoms are in all likelihood related to the vaccines, I will say that what he is going through is exactly how I feel having been diagnosed with B12 anemia.

I never got the vaccine, but I have had terrible anxiety induced indigestion these past two years brought on by the stressful work environment I have been subjected to. This past summer my heart rate would routinely go up to 110 just walking down the street, and I would feel faint, light headed, and incredibly fatigued. The clinic in my town initially thought it was dehydration, so I started upping my magnesium, potassium, and sodium. When it didn't get any better, I got my blood work done, and learned about B12 deficiency and anemia.

Evidently B12 is primarily found in animal proteins, which I do eat plenty of. I don't think I was absorbing as much of the nutrition from these proteins though due to my indigestion.

If any of y'all start to feel like this, and have not been vaccinated, please do look into your B12 levels! I had no idea how important B12 was to overall health and well being until now.
