I make it a point to not have a paper delivered, and I try not to catch the news on tv... for these reasons.

during the enactment of a flight that crashed in the everglades back in the 70s, I was not given proper medical care (I was a pretend victim) and ended up nearly dying with heat stroke. (Seems they didn't learn much from the mock up huh?)
It is just another of my near dying times... but what affected me even more is that later, in the Air Force Auxillary, I worked with the guy who had actually gone into the plane well to try and fix the gear, and had lived (though shattered) because of this... and my being in his vicinity at any time triggered him... (once he learned of my connection to the flight)

My brother in Boston was the crew chief (ground) that authorized Flight 11 to fly on that September 11th. He is triggered so, and has guilt that if he had only found something to hold that plane on the ground, all those ppl (and friends) would still be alive.

to be on the opposite side of a trigger is tough too... seems there is nothing we can do quickly to calm our triggers... we just keep keepin' on...

you are not alone, in fact, so many many of us in the world are troubled by trauma... and it makes it tough to feel safe anywhere, doesn't it?
