I have had problems with anxiety. Heart racing, jittery, weight loss, constant nervousness. I have tried a few anti depressants which only leave me feeling just as jittery. I was prescribed Ativan and Xanax for the shakes and jitters. Recently I have had my thyroid re-tested and my level is 0.6 which has dropped in the last 5 months from 1.8. I am still told by one of my doctors that it is still in the normal range and not to worry about it, and to go see a psychiatrist about more meds. I am wondering that even still in the wide spectrum range of 0.2 -4.0 if this could be hyperthyroid and the 0.6 is not a normal level for me. What other tests would show thyroid activity?
