How long with Hoshimotos

I went to another doctor yesterday, and without so much as an exam of my neck, or a listen with a stethoscope, he told me he would not treat me with synthroid because my thyroid labs are normal. TPO over 600, but thyroid labs normal. Symptoms debilitating, quality of life really bad. Vitamin D low so I take 3000 units per day of chewables. Testosterone also low, but this doctor actually came out and said to me I'm a woman, I dont need testosterone. Give me a break, going to get on a thyroid diet of some sort as best im able to. How long will it take for my labs to be abnormal enough to be treated? How much longer do I have to feel like this? When will I know my body is in serious trouble? It seems that is what these doctors at waiting for. So in the meantime, I will be worried to drive far with two kids, losing my ability to concentrate and live normally like I used to. This is my fourth doctor and I'm tired of being ignored but it seems to be how it is. How long am I going to wait until my labs show how sick I am?
