I'm not OP but I've experienced the dynamic that she describes (or at least something very similar).

Why not address it in session? Because for some reason it just seems to be impossible. I might go into session with the full intent of addressing it all but then some automatic dynamics just take it over and things go the way they go. At least for me those things are not under conscious control and that's the reason they cannot be addressed cognitively.

I'm not saying it's impossible to make sense of those things and resolve them eventually but according to my experience it takes a wise and knowledgeable T who has the patient to wait it all to roll out. In my opinion the OP and her T are doing great work right now, with optimal pace and I'm pretty sure that one day it all pays off. But the process is what it is, it will be dictated by the OPs unconscious dynamics and the process takes as long as it takes, there's no way to rush it.
