Trauma and PTSD are complex problems to even talk about much less overcome. To me this quote talks about how people with trauma have fight, flight or freeze responses that make them act in sometimes hurtful ways.

They also have pain that requires coping skills that take them away from being their true selves.

These behaviors are not who they are. However, they and the people around them judge them as their behaviors. They cannot reconcile who they truly are with what they do.

Imagine someone who abuses alcohol to self-medicate and then gets fired. They want to work and believe in working hard, but their survival skill gets in the way.
