@shimmerz , can we stop for a second? I have a couple of questions for 'the rational part of your brain that we'd all like to think is usually running the show.', if that's ok. Consider this thoughts and questions from left field. (Again)
Is there an actual, real world as experienced by most people, reason why you need to leave the house where you are currently living? Because, up to now, my understanding was that the need to escape exists in your head, but not in the version of reality most people experience. Those are both problems. They are similar problems, but they are not the SAME problem.
The same with 'she doesn't know where to go' or how ever it was you said that. (Can't find it again. :() Before we set about helping that 'part' decide what she needs to do now, maybe we should ask, does she actually NEED to do ANYTHING right now?
Approaching this from a different angle, if I've got this right, the deal with traumatic memories is that you experience them like they are happening now. There isn't the separation between 'over there, back then' and 'here and now' most people have. (I really only have my T's word for it that this is how memory works for other people. :bag:) So, from here, it seems like one of the things that's going on is that this 'part' sees a situation that looks similar, believes it to be a PAST situation, and is setting about to solve THAT problem, not the actual current problem. While it's tempting to go off down the garden path of dealing with an old problem, it's not necessarily the most useful thing to do if you have a somewhat different current situation.
Right now, what's the actually current problem? Finding a safe house? Keeping the wayward part from hijacking the show? Something else?
