What are you eating and what supplements are you taking?
Personally I would stay far far away from thyroid meds, but I say that because armour thyroid is what tipped me over the edge and spiraled me into this whole mess. In general though, I think it's safer to feed the body nutrients vs. supplementing with hormones, especially synthetic ones.
Have you tried taking pantothine for your blood sugar? It works wonders for me.
Also, in general, I think its really important to understand the reasoning behind your adrenal fatigue and to focus on healing methods that pertain to your particular version. We all got here by way of different routes. Why do you think you are sick? Do you have digestion issues? Heavy metals? Other toxins? Too much stress? Over working? Toxic thinking. Toxic foods?
