Just wanted to let you know that I do continue to drop in on you from time to time, just haven't had much in the way of substance to add.
The issue of having "the antenna going up" is probably a universal problem. I know that it is for me. I can process alternative possibilies until the cows come home, but I still suffer those awful physical sensations until something happens to assuage my fears.
Maybe it's post traumatic syndrome, but I have yet to shake my panic attacks, even when there appears to be nothing out of the ordinary happening. They happen less frequently now and aren't quite as intense, but it's uncomfortable all the same. My thinking on that is that the pysche, having been put through so much for so long, is now trained to be on high alert and has to be gradually weaned from the chemicals that once dominated it's system.
Of course, this may only be one of any number of things that perpetuate the struggle.
