The fundamental issue in resolving traumatic stress is to restore the proper balance between the rational and emotional brains, so that you can feel in charge of how you respond and how you conduct your life. When we're triggered into states of hyper- or hypoarousal, we are pushed outside our "window of tolerance"---the range of optimal functioning. We become reactive and disorganized; our filters stop working---sounds and lights bother us, unwanted images from the past intrude on our minds, and we panic of fly into rages. If we're shut down, we feel numb in body and mind; our thinking becomes sluggish and we have trouble getting out of our chairs.
As long as people are either hyperaroused or shut down, they cannot learn from experience. Even if they manage to stay in control, they become so uptight [...] that they are inflexible, stubborn, and depressed. Recovery from trauma involves the restoration of executive functioning and, with it, self-confidence and the capacity for playfulness and creativity.
