At times, I have felt like I was dying. but my TSH was never as high as yours. I have only been on Synthroid for two weeks and am feeling much better. However, my doc said it could take six weeks or longer to notice any differences, so I guess I'm lucky. I'm still fatigued, but I don't feel like death is knocking on my door anymore.
Also, as stated on previous forums, hypos tend to have low D and B 12, plus overall low vitamin levels. Make sure doc checks your vitamin levels and that you are taking supplements. Low vitamins can make you feel really bad.
Get some rest. Take it easy. I have found that stressing about being hypo makes my hypo symptoms much worse.
Take care
