my son use to have horrific anxiety attacks. we eventually found out he had a low thyroid problem. He is properly treated with Armour Thyroid. He takes 5 grains daily (as do I) and he has not had an anxiety attack in almost 3 years. Basically they are gone.
the only thing that helped a little with them while he was getting up to the dosage he needed of Armour was clonazepam. He no longer takes anything except the ArmourThyroid.
You might like to check out the info at:

along with the links at the bottom of the page to the stories of patients and articles. there are a couple of articles about anxiety being linked to thyroid disease.
take care,
Cathy
