Thank you @claytamos
I finally got the papers for the blood tests. It was too late for the magnesium since I stopped using it after getting sick each time I retried. But when I finally felt better, I went to the lab for the tests.
The blood was fine, although my vitamin D was way too low, it was even lower than the minimum requirements, so I had to quickly start with supplemented D. Which I am taking each day, except when I forget 🙄
I seem to feel better overall now, although I am still not the way I used to be. But I am hanging in there!
