Trauma is a result of overwhelming or terrifying events or situations.  A person may experience an actual event or be a witness to an accident.  The person may become overwhelmed emotionally, physically and mentally.  Exposure to traumatic events can cause feelings of terror, intense fear, helplessness and physical reactions.  These events can often produce lasting changes in your emotions, thoughts, your body's stress response and how your body feels.  The impact of traumatic stress if unaddressed can be long lasting and can have a significant impact on your emotional and physical health.  Children are more vulnerable to the effects of trauma due to their dependence on adults for their care and safety.  Children often find it hard to manage their behavior and calm themselves down.  Some people may develop Post Traumatic Stress Disorder which will require specialized treatment.
