Trauma is defined as the emotional response to an extremely negative event. Trauma is a normal reaction; however, the distress may exceed one’s ability to cope. Trauma leaves indelible changes on the mind and brain. Trauma survivors often have difficulty coping or functioning normally after the event. They may develop anxiety, anger, sadness, or PTSD. They may experience symptoms such as sleep disturbance, appetite disturbance, depression, anxiety, substance abuse, and low self-esteem. Their relationships and ability to function at work may be disrupted as well.
