What you seem to be describing (pretty darn well), is hyper-vigilance. I too was in that mode for my entire post-abuse life. It got only worse as time went on. It got worse at a hyperbolic rate.
I use to travel (fly) nearly every day around the country and meet with A-level university deans and presidents. The TSA people pushed my buttons every stinkin time I flew. The yelled, they screwed-up, they were mean to old ladies, they shoved children...they were flaming assholes. I would BLOW up on a nuclear scale. They would not even call the PD unless they were standing right there anyway. I would give them a verbal dressing-down in public that would literally shake them. The state/local PD would actually never step-in. Then there's the other side....
I had a meeting with a dean in New Orleans who fully (fully) reminded me of one of my perps. I literally went into a panic attack and series of flashbacks right there in his office...and he could sense it but did not know it was his extremely aggressive, macho bravado that was rattling me.
Rather than close a large sale, my objective became to get the hell out of his office. All of a sudden, I found myself on the sidewalk in shock.
So...if yer wondering if you are alone in that aspect...no.
We all had to SURVIVE by different and unique means. Only God truly knows what we went through.
