Any type of 'healing' does take time and patience, but equally you are right that you might have to be 'pushed'. I'm pretty sure that most trauma sufferers would rather avoid talking about their trauma. Talking about it hurts - so natural reaction is to avoid it. Any trauma therapist should be aware of this, and push you - at the right time and right pace. It's not going to be a miracle solution that happens overnight, and completely re-traumatising you by pushing you too far is not the answer. Between you and your therapist, you should be able to find a happy medium (okay, it's not 'happy' but hopefully you know what I mean!).
I'm generally a tightly closed book, but equally my therapist has recognised this in me. I have explained to her that I need to be pushed, in order to open up, and talk about what's bothering me. She also didn't need me to tell her that, but my confirmation has made it easier for her to 'push' and me to understand what she is doing and why. If you have seen your therapist for a long time, and he/she still hasn't worked out that you need to be pushed, or simply doesn't bother to push you - then I think you seriously need to either re-evaluate your therapeutic relationship or find another therapist. It can be a bit frustrating to spend half an hour or so of your (precious) therapy session reviewing things, but it really does pay off in the coming weeks. A chance to chat about how you think you are doing, how your therapist thinks you are doing. What you might need in future sessions, how they see things for future sessions etc, etc. Equally there are many therapists out there, who will happily sit and listen to whatever and take your money, without actually 'helping' at all.
Sometimes (a lot of times for me!) it's hard to express what is going on for you out loud. I actually think it's okay to write things down and hand your therapist a piece of paper, for them to read. It opens the lines of communication. (Slightly off topic but relevant - there is currently a government health ad/campaign about bowel cancer. The 'tag-line' said by the doctor actor is "it doesn't matter how you tell me- just tell me". ) We are often too embarrassed or ashamed to talk about all sorts of things, but are doctors and therapist are pretty un-shockable. Find a way, any way, to open up to your therapist. Good luck!
