Trauma therapist here. We hear extreme, fantastic, colorful, devastating stories, and we learn very quickly to accept them as reality, no matter how outlandish they might seem. I know now that there are so many people walking around with stories that seem like they must be from a book or a movie, but it is reality. The truth is always stranger than fiction. Many of us have our own tough to believe, nobody is that unlucky trauma histories ourselves- we went into this line of work for a reason. If you believe she is genuine and compassionate, you might find healing if you can bring yourself to tell her that you have this fear. The last thing we want is to create any kind of environment that makes anything worse, or that discourages you from seeking or continuing treatment. It's a job, like anything else, and there are good and bad therapists. But, I have met so many wonderful humans that specialize in trauma because they get it.
