Thyroid medication and anxiety. I do.

I have been diagnosed with hypothyroidism almost 9 years back and have been taking 75 mg thyronorm since then .for many years it was fine but i always used to think the medicine makes me hyper or anxious .Last year December i stopped the medicine for a month and my tsh was 10.3 after the test .i started taking my medicine again 75mg ..it level became normal after a m onth but i feel anxious and it's kind of a morning sickness which I feel every morning after breakfast . reduced my dose to 50 mg but the TSH is not in control .can some one suggestion what should I do ..? Are these medicines making me anxious or the sickness in morning is related to the medicine ..i feel very anxious and had panick attacks also
