Jane, it's a beautiful sunny late summer morning here in the Great Lakes region of North America. I know it's night where you are, your country is across the IDL and it's late winter in the Southern Hemisphere. We are all bound to the same Earth, all in a primal struggle to survive. My new T says that almost all behaviors ultimately serve a survival purpose, even if hard to discern at times. We know all of the major PTSD symptoms are about survival, all designed to make us fight, flee, or freeze. As I said, it is an artificial construct to put a moral judgement on behaviors that are so natural and instinctive - your sister needs to get the chip off her shoulder if she thinks she is so high and mighty that she could never be in such a position as you were - it really could happen to any of us.
