If you have a highly sensitive nervous system, there's nothing defective about you, (though it can feel like there is!). You need someone who gets it and has years of experience guiding and supporting others like you. 

When you're exposed to something that is too upsetting for you to process in the moment, that experience gets "stuck" in the body. But you don't have to be controlled by your past anymore. Trauma therapy can help access and heal the trauma for good (all without re-traumatizing you).
