Trauma

Mental trauma (or psychological trauma) refers to those psychological, emotional and even physiological abnormalities caused by relatively serious injury events in life. This abnormal state may be slight, and after a period of time (usually within three months), self-adjustment can heal automatically. But there are also some trauma effects that last for a long time, often even for life. For more severe trauma, it is called "post-traumatic stress disorder (PTSD)" in the classification of psychology and psychiatry.
