I just want to lend support for your commitment to honour your needs while being open to the proposed program. At the least it shows resolve on your part to see that there might be benefits from the suggested program but that you need to find compatible areas to blend in with the sessions. Otherwise, if the point seems to be entirely therapist or insurance-driven it doesn't seem right.
Here's where it seems wise to have outside sources, like Walker's book and the links Three Roses suggested, from which to draw further ideas. The advantage of Walker's material for many is that he's traveled both sides of the fence, as cptsd survivor and as a therapist.
There are so many aspects to therapy, and being in it can feel very fragile. Too often it seems like the already vulnerable patient is discounted in favour of programs over which they have no input. Fine, except -- it's
their therapy, and life, that's at risk. The professionals can tend to forget that their service and obligation is above all -- to and for the patient, with the latter's input when appropriate.
Hoping you can find a positive outcome with this.
