Maybe I'm flaunting my ignorance (I'm REALLY good at that.), but I was wondering what criteria you folks use to define a panic attack - as opposed to "anxiety" "anxiety attack" "feeling panicky"...
Last week (I think - time has been a blur lately) I was admitted to the ER for what I knew was going to be a panic attack. I had been holding it down for about three hours before I went in (clinic and urgent care were closed

). While I was there, symptoms continued to escalate, in waves - every 20 to 40 minutes. I tried everything to quell it, to no avail (hence my user name). After about two hours of tests, I recieved 1mg of Lorazepam in the arm. (Aaaahhhh... Finally normal again! After close to six hours of terror.)
The nurses kept referring to my state as a panic attack. I, however, was under the impression that I was just experiencing "pre-panic anxiety" or "that damned panicky feeling". I've always only counted episodes (no, I don't keep score) that end in paralysis and unconsciousness to be a "true" panic attack.
Here's my question (finally). Was I experiencing multiple, discrete panic attacks, or was I merely on my way to one?
Opinions? Experiences? Insight? Help???
