Agreed, Kas_Can_Fly wrote an amazing post, I "like"it a hundred times.
There aren't many things I feel sure about when it comes to therapy or healing, but one of them is that pace and intensity and what is required are totally unique and different for each person. A good therapeutic relationship and context is one in which both parties work together to figure that out and to make it happen. A less successful, to varying degrees, therapeutic situation is one in which that doesn't happen.
But however much you talk about your trauma in detail or not, there is one part of healing that I think sometimes is overlooked,and it's the one the OP is getting at. Any process that deconstructs parts of who you are and who you have always been, must, by necessity, work to reconstruct those parts afterwards. Building a new, or modified, life for yourself is every bit as critical to healing as processing your trauma, and I think the reason that it is so daunting, other than those already outlined, is that some therapists forget about it, or try to move you on right at the point at which that phase of the process is required.
"Good, your trauma is all processed and your symptoms have eased... thanks for coming!"
At which time you're left wondering who you are, what to do, and how on earth to learn to live in the new, less traumatised but very unfamiliar world in which you find yourself.
The extent and impact of this is different for everyone, but I think that many of us baulk at the prospect of recovery partly for this reason, and wonder if we will ever be able to do it justice, even if we can get there.
Like everything, communication with your therapist, insight, hard work and realistic goal-setting are important. Not that I'd know of course... I'm a long way from being there, but I'd like to think that some day, figuring out how the new me is going to live in the big bad world, might be a problem I'll face.
