People handle crisis in diverse ways.
Have you ever asked yourself why you cry watching a movie, but when confronted with a crisis, or a loss in your life, in which you need to make vital decisions, there's no time to cry until the crisis is over, and then you ask yourself : "Did this really happen, or have I been dreaming" ?
Some people freeze and are unable to make decisions, while others find unknown strengths and act in ways they would have never imagined, in order to handle situations that they would have never solved in a regular day.
How people behave after being exposed to a traumatic event can also vary. Some people shut down and would not talk about the experience, while others might feel an urge to share their feelings, or talk about their experience numerous times to friends and relatives.
The sad part is that relatives and friends don't want to listen to you , mostly because of difficulty dealing with their own grief and pain.
In case of an event where numerous lives have been lost, and a person witness the event, it can cause mixed feelings related to "being alive" and grateful, or "being alive " and feeling guilty about it.
In each of these scenarios, talking about the experience to a professional who has been trained to deal with crisis, and with survivors of attacks, can help you keep a healthy marriage, keep a good friend, but most of all, can help you stay emotionally and mentally stable.
