So sorry to hear of your troubles. you can absolutely get through this, you just need the right support. I'm fairly new here, but like so many on these boards I have been doing Nutritional Balancing for about one year. A hair mineral analysis by Analytical Research Labs would be a very good place to start. It will give you a very accurate picture of your minerals on a cellular level. These correspond to your adrenal, thyroid, digestion and overall well being. As well as let you know if you have any toxic metals.
It sounds like you may need some very gentle support with your adrenals, where the supplements you have been taking are designed to rev up your adrenals and give you more energy.
After your analysis they will give you a very basic diet plan as well as some supplements to take that will no doubt help your thyroid and your adrenals.
Check out these links. I think you will find them very informative.
