Hey there, all the symptoms you are describing can be directly related to your thyroid issue. Too much or too little, will cause all of it including the sleep problems and brain fog. When I was hyperthyroid, I was jumpy, nervous, and really paranoid. You should really see an endocrinologist, they specialize in that system and you need to find one that doesn't just look at your lab numbers. There is a reason your thyroid is wonky and they can figure it out. I know it's a pain to add another doc to the list, but my endo saved my life. Good luck!
