When you say your hyperthyroidism
is back to normal now, does that mean you are having normal thyroid functions or they are showing readings suggestive of hypothyroidism? Are you still on anti-thyroid medications? If so, then may be you should see your Endocrinologist
if you haven't seen him or her within last 6 weeks. He/ she might look at the need of lowering or stopping the dose of anti-thyroid agent. If you were never before diagnosed to have anxiety
, then wait for the thyroid to really show all values in normal range with your Endocrinologist's advice, then you will start feeling better. I don't think you have genuine anxiety to rush for psychiatric help as fluctuations in thyroid while you have had a history of hyperthyroidism are know to cause such weird symptoms. Take care. If continues to worsen then see the doc ASAP.
