Davit/Luciana,
My understanding is that panic is a escalating process... or think of a stairway... that needs each step to continue. Literally, 'removing a step' disempowers the process and ceases the process from moving forward. Obviously, easier said than done. Breathing, relaxation techniques, questioning unrealistic thoughts, identifying (and avoiding) triggers all remove the proverbial 'step'.
I'm an RN... used to work in cardiac surgical units... and this is all pretty logical. Having said that, I'm sure some people are predisposed to anxiety, just as someone may be predisposed to diabetes or weight issues.
The 'key' w/ this program and other methods I've read (Linden/Barry) are to know yourself and your panic process so you can remove a 'step'.
All of this you know... I can tell by reading your post. However, it is nice to hear another person restate it.
Lastly, it's been September since I've been to an ER... not long for some, for me, pretty good. I've had about 3 'bad' panic attacks since, but have been able to 'breathe' through them... very hard AND scary, but I did it. (Once, literally breathing into a brown paper bag... BTW, it works!) For me, breathing correctly, above all else, has been key. Whenever I get stressed I focus on 'boxed breathing'... and it helps a lot.
My panic usually occurs from thoughts... usually initiated from a sensations. The breathing and reading info on this website have been very helpful in keeping myself calm. Again, not easy, by any stretch of the imagination.
Take care!
