Ah..thanks for mentioning the "rewiring" thing in your post, Pam (and thanks for being good natured about my reference to you lol?).
I think this re-wiring idea is completely valid. YES traumas the like of which cause PTSD DO affect brain function and structure. (more so with repeated traumas...apparently what doesn't kill us does not necessarily make us stronger... )
BUT there ARE ways to rewire the brain...the self talk, self soothing, distraction, MEDITATION...as I've mentioned before brain scans show an actual shift from the anxious right hemiphere to the Left "feel good" frontal areas when one meditates...and the more one does it the more lasting the changes!
