pmi,
Yes, the good old "Geritol" approach, LOL!
Actually, I do tend to run almost anaemic, and a previous PCP thought I might actually have Gilbert's syndrome (very common, under-diagnosed, not considered serious, but tiredness-causing), so that might be a complicating factor for me. Interestingly, she specified that my low-ish red blood cell count was NOT due to any iron deficiency.
But you do bring up a valid point, and others would be well advised to check for other possible factors, too, including thyroid levels!
I've had numerous comprehensive blood panels in recent years, and nothing really stands out.
As for prayer, I do appreciate the sweetness of that sentiment, but speaking as a non-religious person (like about one third of Americans, now), I think you should save that for like-minded people.
My feelings are that more people should have more respect, faith, and "belief" in science, and the lack of that in this country is arguably responsible for the problems we've gotten ourselves into with this particular illness.
Having gotten that off my chest, I want to express my sincere HOPE that you start feeling better soon, as you sound like a very lovely person, and I do thank you for your expression of kindness and help.
