I never had to push for treatment at all. Matter of fact, I was given medication before I even knew that my t3 level was elevated, but what information I've gotten on hyperthyroidism, I got for the web and not from my doctor. I also was diagnoised with clinical depression and I believe that this may have been my problem all along.
Well this all sounds so familiar. Do you have any idea what a high T3 is? All I was told was that my T3 is over 200, that I have mild hyperthyroidism and I was given medication. I had a TSH done 3 years ago and I assumed it was normal since I never heard from my doctor, but I've had the same symptons for years. They are pretty much the same symptons you have. The only kicker, I'm considered morbidly obese and I thought hyper meant you loose weight. Go figure!
Unfortunately, you have to push for treatment. I was in your exact situation, slightly hyper, felt like hell, so I had to throw a fit to get antithyroid medication. It's made a huge difference in my life. I'm hyperthyroid again b/c I'm pregnant but atleast I know what's wrong with me. I was in your situation for years being told I had clinical depression -- but thyroid was the root of my problem, not depression. Get copies of your test results and keep at it. Good luck.
