Smushroom. I just wanted to send you some courage and empathy in tackling this issue with your T. Honestly, more and more as I read, I begin to feel a little cautious at recommending what anyone else should and shouldn't do in terms of their therapy and their interaction with their T etc. I think there are as many different styles and deliveries of therapy as their are therapists and clients, and beyond a certain point, there is no such thing as right or wrong, only what works for you and, to a certain extent, your T as well.
I don't believe that therapy is or should ever be completely as per the textbook. People aren't that straightforward and human dynamics play an enormous part in how the process unfolds. I know that aspects of the relationship I have with my T would be considered unconventional at best and would be frowned upon were I to share them on this forum. And because I am a little sensitive about such things, I would probably feel threatened and defensive, hence the fact that I refrain from sharing. But do I think that my T is good at his job, unyieldingly professional, focused on my best interests, goal-oriented and motivated? Absolutely, a resounding yes I do, and so really, that's all that matters.
I guess I say all that to say that I would really encourage you to identify exactly which aspect(s) of this situation aren't working for you, and to focus your attention on dealing with only those. If she is a qualified psychologist specialising in trauma, then I think it's reasonable for her to give you an explanation as to why she isn't prepared to deal with your trauma. There may well be some reason, in which case you deserve to hear it, and to give it due consideration. If there are other aspects of your communication which you feel are failing, then you both deserve the opportunity to address them, at which point it will be up to you to decide if they can be remedied or compensated for, and what to do about it if they can't.
I guess I say all that to say that "by the book" doesn't have to be the best way, but "what works for you" does. I know you know all that too, but really just wanted to send you some encouragement to get out there and advocate for yourself - you so deserve it.
