Well, logically you got no other option but to GET BETTER. I had many of your symptoms and it was due to adrenal fatigue. As i get better, they go away. One of them was the hypoglycaemia.
Best thing you can do is just recover on a adrenal fatigue protocol and see how you feel. Dr Wilson and Dr Lam have a lot of information.
That video is a extremely potent piece of advice to start.
If a Doctor takes your opinion but doesn't give a adequate response that makes sense, thats a sign of ignorance, and it generally shows up in other areas of their work.
