If you're gluten and lactose intolerant, you should be on a gluten
diet, as well as sugar and soy free
. It's not an easy diet to be on - I know, I'm supposed to be on it, too, but it does help.
I'd strongly suggest that you ask to get vitamin B-12 tested since you have that never ending fatigue. Although fatigue is a common symptom of hypothyroidism, the "I feel like I'm going die" type is often a vitamin B-12 deficiency which also often goes with hypothyroidism.
