There are different degrees and types of trauma. All are embedded in the nervous system and heal through mind/body techniques. Trauma can be caused by many events including abuse, car accidents, sudden loss, and being a victim of crime among others. Many hold trauma from growing up in a dysfunctional family. This may be held out of awareness. Triggers can cause reactions that are out of proportion to an event.
Chronic anxiety, and depression can also be the result of trauma. Research has shown that talk therapy is not enough to heal or remove the debilitating effects of trauma. I have years of training in trauma targeted therapy, EMDR among them. I have utilized techniques that have unburdened many people so that they can live life free of the past.
