I had an entire thyroidectomy several years ago and never felt like myself even on high dose synthroid. I like you didn’t feel my endocrinologist was listening as they were only interested in the fact my TSH was low enough not to stimulate any remaining thyroid tissue. I never felt right until another doctor started me on NP thyroid in addition to the synthroid. I wish you luck it is a miserable time until you get back to feeling normal.
