all things that arise pass away: that is one of the most profound insights i have ever had. if you can focus on hanging on, enduring, perservering, not looking at the "bad stuff" for a while, it will (almost certainly) recede, and dwindle and then it will be small potatoes.

in the mean time, when you are panicked, try these management skills:
1) focus on your breathing,,, slow and deep (if you are panting, use a paper bag to breathe into)
2) count your breaths, 1001,, 1002,,, 1003,,, 1004,, and count slower and slower,,, this will slow your heartbeat
3) delay doing anything, even movement, unless you are one of those people who finds movement calming
4) distract yourself from your thoughts by reading anything in sight, cereal boxes, magazines, any thing light and frivolous, or listening to music, what ever works for you
5) get something nutritious to eat, a granola bar, an apple, anything that is sweet (you burn a lot of adrenalin having a panic attack)
6) take a break, get away from where you were when you were having the panic attack,, change rooms, change chairs,, change something so your body will understand that the "bad thing" is over, gone, no more....

these are the skills i learned and used to live thru some pretty horrific panic attacks, and later, deep anxieties. hope they are of use to you ~
