My issues are different but I also experience exhaustion due to a thyroid condition and afib. Although I have spoken to every doctor about feeling exhaustion none of them ever address it. One even told me no one has ever told them this which is very hard to believe. Different groups here have made me realize it might be very connected to your diet. You have to have a healthy diet. I have found this very challenging in the covid world where going to the grocery store is another difficult chore. And you have to exercise also which sounds trite but I have found it does give me energy. I also found some of these home remedies also have helped me. For example, eating foods with cinnamon help. I make an apple pie every other week for the apples and the cinnamon. I also take a zone diet multi-vitamin which is expensive but I feel it helps. When I let any of these things go I feel the effects. I wish i could just find a pill to do all this but have not found it yet. Hope this helps a little.
