I had that really bad before I was treated for hypothyroid. I would have severe panic attacks first thing in the morning, and sometimes would just feel frozen, and very nauseated, even have dry heaves. I tried to tell the doctors over and over again that I felt sure that I had a thyroid problem, but my lab tests just didn't suit them because I was borderline hypo. I also had intermitted severe fatigue spells where I could hardly hold up my head, and it was very difficult to get up in the mornings, which all these things are better now, even with a small dose of Synthyroid. Part of the problem with diagnosing this is because (I believe) it ebbs and flows, and they just can't catch this doing a lab test once a yr.. Anyway, that's something you might look at. I did have a good bit of stress in my life at the time, still do, but I guess the Thyroid helps you deal with the stress, and it affects the other hormones like cortisol.
