It is naive to believe that such attacks are over. A few will run to isolated places, where they believe that they will be safe. Most will attempt to live life as normally as possible. Anticipate the future. While none of us can predict the future with certainty and while it is unpleasant to anticipate negative events, it is helpful to psychologically prepare one's mind for more bombings and random acts of violence.
Mental preparation helps to reduce the shock and trauma associated with terror.
Beware of the pitfall of fearfully dwelling on possible future terror. Doing so will increase anxiety. Anticipate the future but don't become obsessed by it. It is important to develop connections with other people so that support systems are in place when tragedy occurs. Research has shown that social support is the most important factor in surviving life-threatening experiences.
