A Psychodynamic therapist or a Humanistic one will incorporate childhood and PTSD into sessions. Sadly CBT is based in the clients present and 'here and now' so does not incorporate the past. CBT is good for phobias and mild anxiety/depression, but only when psychodynamic therapy has supported most of the work.

The therapist sadly won't change their model, so I hope you can find a psychodynamic therapist to help.

I've been with the wrong t for 9 years and as it was the wrong model (but I had maternal transference) it's taken years to make progress.

CBT therapists are trained to not work with transference usually.
