WOW - you have just written my life story! I have had the same complaint for five plus years. My doctor finally agreed to do a COMPLETE BLOOD WORK UP and found three things that do not show up on regular blood tests. Two issues have to do with iron...I do not have enough iron in my blood stream but I have too much iron in storage. So, not only do I have iron deficiency; but, also iron overload; but, I am NOT anemic. Right now I can not take any vitamins or supplements with iron and I can not give blood. I am seeing a hemotologist and going through a battery of tests to see if I have a hidden infection that is draining my iron supply. Too much iron in storage can be deadly and we will start addressing that in January after I finish a Vitamin D treatment.
The third thing wrong is extremely low Vitamin D. I am currently taking 50,000 units of Vitamin D once a week for six months. With my doctors' approval, I added a supplement called GS-6. GS-6 does not contain any vitamins or minerals, it contains peptides and came highly recommended as an overall health improvement. Three days into the combination of the two, I could tell a huge difference. Between those two, I feel so much better, that, I don't even realize I feel so GOOD, until I really am tired, and rather than focusing on being tired, it makes me realize how good I have felt and for how long.
My doctor made every excuse you could think of for me being tired and I let her. One of the things is that I take care of my ill and elderly mother-in-law. I finally realized that if this my m-i-l with the problem, I would fight for her to get treatment. I had to go into my doctor's office and insist she do something or I would find another doctor! So, fight for yourself! Exhaustion is NOT normal. You deserve to live a full life and not just be thankful for getting through the day. God Bless You and keep trying to find the answer!
I am amazed at how many people are low in Vitamin D. My doctor told me that even after I finish this mega treatment of Vitamin D, that I will still have to take 5000 units of Vitamin D3 per day for the rest of my life. But, it is worth it!
I realize for my own health, the iron issues are much more life threatening; but, at least now I have some energy and feel like I can face those issues.

Two things I forgot to mention - my doctor also had me treated for sleep apnia. I disagreed and almost refused to be tested. However, I tested as having severe sleep apnia. Because I have not gotten use to the machine yet, I am now aware of when I am not breathing and I wake myself up to take a breath. I am sure once I get use to the machine, I will not wake up as often.
The other test was to check my liver function and in the process found other problems that required more test and found my gall bladder was only funtioning at 7% - so it was removed. So, by the same token of taking control of your health and fighting for more tests, do all the tests recommended because you never know what they will find.
Ironically, after having to fight so hard to get my doctor to do tests, once started, there was a domino effect. However, it has all been worth it and I do have a lot more energy! God Bless!
