I feel as if noone understands what i am going through.
Yah, we'd all like that. But it's not the doctor's job to feel our pain. Try a social worker or talk therapist if you want that kind of empathy.
There are 2 general schools of clinical medicine: the interventionists & the noninterventionists. Interventionists like to order every test there is, and try all available treatments recommended by their specialty. (Not just to benefit the patient -- more often to protect their butts.) Noninterventionists are more skeptical, more wait-and-see.
Unfortunately, many of us on the board have had unhappy experiences w/noninterventionists. The sort of doc who won't do anything until it's crystal clear (by his/her lights or reference ranges) that there is a very serious problem that needs to be addressed. Usually by that time years of suffering have transpired. Noninterventionists are also more likely to attribute symptoms to psychological causes & to offer referral for counselling, or psych meds.
Depending on your point of view as a patient, it could be you are mismatched. Perhaps you would do better with a doc who is more of a noninterventionist.
The other factor that is at play here is the complexity of our expectations. Most of us expect that doctors have the answers, and that they will be able to help. Doctors & pharmaceutical companies set us up for these expectations.
But the truth is that much of medicine is trial & error. There is no such thing as medical omnipotence. There is so much about the human body that is still not known. The peculiarities of our unique responses to medication are not well-understood. Many of the meds that are highly promoted as the answer to our suffering are not without side effects.
The best remedy for your situation is to find a doctor who resonates well with your own perspective. And to become as knowledgeable as you can about your own health. Get copies of your test results. Learn what they mean. See if you can figure out what treatment paths you would like to try. Which tests you can do without. You have a right to refuse any test or treatment. (Otherwise it's assault & battery on the doc's part if he/she forces you.) There aren't an infinite number of tests & treatments for thyroid. It's not that tough to learn the ropes.
Otherwise, you're at the mercy of the system.
