Hope, Could it be that she told you that in never happened to her in the context that she understands your experience (best she can as it has not happened to her). I think when others try to share their understanding, many people think (You can't understand-did it happen to you? then how the heck do you know?, etc)
As far as the active listening and summarizing back what is said being a technique-In trauma, stating the information back and naming feelings and thoughts-(in a somewhat matter of fact manner-unemotional) does have purpose. When a client is very reactive and emotional to the content, having flashbacks, nightmares, etc., stating the facts back calmly is intended to be a path to help the client name what happened and think about it with less negative emotion, and to decrease the symptoms. Dont know if I am making it clear exactly, but see their good intent.
Example: A woman client grew up in an alcoholic family and was often left on their own since being a toddler, or as long as they can remember. There were no adults to take care of them, to feed them and protect them. Maybe they were responsible for younger siblings as well. Now they bring this to counseling but deny it has anything to do with their adult life. The T wants them to open up those wounds and see the correlation to the adult life they have created. Finally they do, and they are emotional and cry, stating that they were all alone and sharing events. The client becomes angry at the parent who failed at parenting-rightfully so. At one state the therapist is in that place with them (maybe causing tears even). As time passes and more content comes, the T may paraphrase the clients thoughts and emotions, and with less emotion. (the goal is to help the client seperate self from the event itself.)
A therapeutic technique for trauma is "telling the story" over and over and over, until the traumatic even becomes an event of the persons life and they are able to talk about it without falling apart or being triggered. The T may use many forms of therapy to tell this story, such as Art Therapy or Drama therapy, or others, as we all learn and connect best in different ways and with different senses. (hearing, writing, seeing, etc) The key to being a good therapist is more than their education and such, it is like being a good dancer, being able to move in the right direction with any given prompts. The therapy is much more complicated than I am sharing but attempting to summarize.
I still think you are right Hope, and hope you talk to her.
