Trauma, and in particular P.T.S.D. are most often thought of as caused by major events such as witnessing a death, having someone close to you die in a tragic way, being sexually abused, raped, physically abused, any myriad of abuses that can happen to children. However trauma is often caused by much less dramatic events.
Perhaps you were picked on as a child or you always felt inferior to your brother/sister. Perhaps you felt humiliated at one time or another. Whatever the cause the end result can often be debilitating. Many problems are a direct result of an earlier trauma whether in relationships, at work, fear of success, fear of failure, Depression & Anxiety, Addiction, Eating Disorders, panic attacks... The number of problems that are created by an underlying trauma are endless.
EMDR & Cognitive / Behavioral (CBT) therapy are intensely effective at delving straight into the trauma and working through it so it NO LONGER effects your automatic reflexes.
