"Time heals all wounds" is sometimes true but not always. In fact it's probably most often not true when it comes to the emotional effects of trauma. Time may actually make matters worse.  The recent unfortunate suicides by two students from Douglas High School in Parkland, FL and the suicide of a father of a child murdered in Sandy Hook elementary school show all too tragically how the passage of time is usually not a cure for the painful effects of trauma. The memory of the traumatic event may remain just as vivid or even more so, and the feelings of loss, guilt, fear, and anger, frequently get worse over time. So the key point is this: All survivors of violent trauma of any kind should be seen by an experienced trauma therapist even if they say they're doing OK. It could be a matter of life or death.
