panic attack today

i had my first panic/anxiety attack today and i have to admit that i really did not enjoy it.  At least, i think that's what it was...i have nothing to compare it to really, but that's what i'm going to call it.  i was at work...go figure...and it was work that got me into that mode.  Again, go figure.  All of a sudden i got very agitated at work.  Stressed, anxious, angry, raging.  It all happened very quickly and took me by surprise.  i also got extremely short of breath.  i panicked big time.  i honestly feared i was having a  heart attack.  But, whatever it was, i did not like it and i do not want to experience that again. i'm sure that i will, but i do not want to.  i know what circumstances caused it at work, so maybe knowing that can help prevent this from happening then.  We shall see.
