What are your exact TSH, Ft3, and Ft4 levels and ranges?

You may need a new MD. I had what you described and the only thing that calmed things down was finding my adrenal insufficiency and treating my secondary hypothyroidism. My BP and heart rate drop to normal levels and stayed there with just a 50 mcg dosing of synthroid. Things got even better with the addition of 20 mg of hydrocortisone a day as well.
