Sensorimotor therapy is very powerful as well.
I think, if neurofeedback works for you, the 'internal struggle' feeling resolves and goes away. And what replaces it is an internal sense of okayness and calm. My CASA youth could not imagine the interior state she achieved before achieving it-- it was unknown to her prior to treatment. And she can barely remember the state of agitation she used to be in now that she is out of it.
