Nothing mystical occurred when I filed a complaint against a therapist, and I doubt it would have even if I had won. I did speak up and saw concretely that my therapist had the same justifications and insincerity he had when it happened.
Over the years I've tried to put myself in his shoes to understand his reality system.

I think empowerment can come through simply living life, pursuing goals, self-care, getting physically stronger. I find most of the equation omits the other person.
