Thank you Junebug. To me, this seems to be what is referenced in post 49 that you referenced above as an EP gone wild. I think I have been mainly driven by EP's over the past 10 years and am attempting to rebuild my authentic self during this time. I am a great believer in the Structural Dissociation model. It fits for me.
I also have wondered if I am Aspie or Autistic and I don't know if that has been all of my life, or whether this last bout of PTSD has created this situation where I am so easily overloaded. And when overloaded I had some really dramatic responses. I still get the feeling that the PTSD is driving all of this though so I am not actively researching the Aspie.Autistic stuff.
As a follow up, I went to this new therapist I have, on Friday. He suggested what I knew he would. Find a place to call safe in the home. Find a spot in the home that you can claim as your own and do self care stuff there. This is so much bigger than that though. The fact of the matter is that I am a lamb going to the slaughter if there is any form of aggression in this house and that is what is activating this EP. And my EP is looking for danger in the house simply based on the anticipation of the cold weather coming. I can 'claim my safe place' all I want to but if there is a perception on the EP's part that I am being threatened, I know what her MO is. This is where I feel the CBT stuff is unhelpful. You can tell ME all you want to do self care, to claim my space, that all is safe and well if I do these things, but based on past experiences unless I deal directly with the EP's direct issues, this is really a waste of time. The main part of me is certain that it is safe here, cold or not. But one wrong move.... and if that EP is activated.... this part can know whatever she has been taught - but it won't have leaked through enough to keep me in the house.
Junebug, if I have missed something would you mind letting me know. There was a ton of information in those posts. I think I understood what you are getting at, but please advise if I have lost the point you were making. Thanks for taking the time to direct me to such great resources!
