Because most trauma survivors don't know how trauma usually affects people, they often have trouble understanding what is happening to them. They may think it is their fault that the trauma happened, that they are going crazy, or that there is something wrong with them because other people who were there don't seem to have the same problems. They may turn to drugs or alcohol to make them feel better. They may turn away from friends and family who don't seem to understand. They may not know what they can do to get better.
Traumas happen to many competent, healthy, strong, good people.
No one can completely protect themselves from traumatic experiences. Many people have long-lasting problems following exposure to trauma. People who react to traumas are not going crazy. What is happening to them is part of a set of common symptoms and problems that are connected with being in a traumatic situation. Having symptoms after a traumatic event is not a sign of personal weakness.
