Kryptonite: Declining Mental Capacity
Not surprisingly, it is uncommon for someone in a disaster or emergency to retain 100 percent of his normal mental faculties. Consider the fatigue, injury, dehydration, lack of sound sleep, and emotional stress in an emergency. Those factors will cause most regular people to become a complete train wreck. With this in mind, carefully monitor yourself and other survivors for depression, anger, frustration, hyperactivity, feelings of intense guilt, ideas of suicide, and any irrational behavior. Do whatever you can to avoid "shutting down" or giving in.
