Traumatized by a trauma specialist. And nothing in place to prevent it.

Reassurance is not a technique, it's a basic facet of normal human interaction.

Seems many therapists are either legitimate sociopaths, or their minds have been so warped by training/programming that they have no idea how aberrant their behavior is.

As for resistance, transference... personally I tend to go with more straightforward narratives... e.g. feeling worse from therapy is just that, feeling worse from therapy.
