Writing a first post... Wing, Trauma is not PTSD. Trauma hurts like a sonufabitch, but it's not PTSD. What your wife is going through... yeah. Two problems: Yours and hers.
My feeling is that she's suffering HER thing and your suffering your own and you can't BE there for her. She might even bring up that she's always BEEN there for you and your shit. ;) You HAVE to take care of yourself, first... you can "be there" for her if you step back and deal with yourself, first. ... and, I have NO idea what that means: VERY good therapist is trying to pound this in my head and I'm resisting. Not sure why, but I trust her enough to say that she is right and I am wrong. :D Yes, Ma'am.
