The main manifestation of death anxiety is the abnormal fear of death, worrying about death, thinking about it repeatedly, and even thinking every day about how painful it should be when you face death in the future, which can lead to panic, hand trembling, irritable mood, and other problems, especially the mood is not quiet every day. From the perspective of psychoanalysis, everyone may have the problem of life instinct and death instinct. Especially the problem of death instinct is faced by everyone, because the matter of death itself is particularly fearful, so from this point of view death anxiety may be a normal reaction. However, if the current situation of death anxiety is so severe that it affects one’s study, work and life, or even if it is so severe that one has no way to be competent in one’s current life, one should actively treat it. For example, medication and psychotherapy, the most important aspect of psychotherapy is to recommend cognitive behavioral therapy, systematic desensitization therapy, Morita therapy, psychoanalysis therapy, etc.
