hashimotos? toxic thyroid? Leukemia?

my thryoperoxidase antibody is over 6000 and my thyroglobin is over 400 ( was only 90 last year). I always have low platelets and with these increasing numbers I'm concerned about leukemia. I had a CBC done today and am awaiting results. My physician says not to worry, I have Hashimotos thyroditis and there's really nothing we do except monitor until thyroid depletes itself. Last year I did get all the symptoms of thyroditis and it was so severe I should have been hospitalized. I still get bouts of tachycardia but not as severe. My body cannot handle stress anymore. I get lightheaded when in stressful situations. I get night sweats now and then. I really don't know if I should "wait " this out. Isn't there any further testing I can do? Oh, my eyes often stare into space a lot as well.
