Panic Disorde
"My experience with a serious panic attack was thought to be the onset of a heart attack. I was monitored, had lab work, even x-rays. No heart attack, my heart was found to be totally clean of blockages. So the doctors conferred that I was indeed having a full scale panic attack. I was given a single 1 mg pill of Ativan. 
within minutes i was calmer, breathing returned to slow and regular, i felt warmer, and secure, clear headed yet a little sleepy.
the other med i take is one 75 mg Effexor XR nightly, and a single capsule of raw thyroid nightly
i do take a vitamin and mineral supplement when i think to.
the Ativan prescription was issued for short term and serious times of panic only. 
it was recommended i receive counsel, as well."
