As was mentioned before, therapists who specialize in religious cult victims and their recovery, are rare.
I was able to find one who has patiently worked with me every week for nearly a year-and-a-half. She even watched many of the j-dub videos, and played them for me during therapy sessions, hitting pause from time to time to explain the details of how what was being seen and heard is emotionally abusive.
In addition to PTSD recovery, EMDR therapy, and an amazing amount of professional patience, she helped me round the corner.
Marriage saved and still together as a family with all of us miraculously having exited one of the most dangerous religious cults in the world.
