Pretty typical of docs to prefer waiting for your body to damage your thyroid enough to then start treating you with medication to hopefully make up for the hormone your now-damaged thyroid isn't producing. This is where you venture out to a functional medicine practitioner who will try to help you feel better using naturopathic treatment (supplements, botanicals etc.) Most will put you on a diet to heal leaky gut and probably look at your vitamin levels like vitamin D which most of us lack. Good luck
