I both agree and disagree with this. The agree part is the science (I'm thinking of Bessel van der Kolk's The Body Keeps the Score) establishes the helpful role of body-based therapy for trauma. In my own healing, mindfulness (as distinguished from meditation, which I've done for decades) took me to new places, as did Tai Chi.

The disagree part is that "never" is not accurate in my view, and in the midst of trauma itself, I think the automatic nature and overwhelming that occurs does not allow for much cognitive processing, if any. Sensory information is more likely to be taken in on a limited basis during the traumatic events. I think the science of it suggests that higher order cognitive functions, the outer cortex of the brain where reasoning and problem solving take place, are essentially offline.

But I don't think the science supports that trauma triggers (compared to the trauma itself) trip the amygdala with the strength of the original trauma, which suggests that the cognitive processing/thinking/reasoning part of the brain is still engaged. It is possible to work to bring the traumatic material into a therapy session (for me it was helpful to learn to recognize the onset of dissociation and then use grounding techniques like pressing my feet into the floor and taking three deep breaths or other breathing patterns), to learn to contain it there, and to develop the ability to move forward from it. It is slow and painful, but I'm not an outlier. I think it may be important to start from a cognitive place that the traumatic reaction tripped from memory or symbolic events (by symbolic I mean things that happen that are not abusive, such as the OP's feeling her T is emotionally reacting like her abusers) is not set in stone, forever unchangeable. In my experience, cognitions and emotions are in dynamic flux, constantly informing and influencing the other. The ability to feel and the ability to think are not mutually exclusive.
