There is always a dynamic balance between human beings and their environment, and anyone will encounter difficulties, stress, or suffer from trauma at some point in his or her life. But in fact the emergency state of stress and trauma itself does not directly constitute a crisis; only when a subjective perception of a traumatic event threatens the satisfaction of needs, safety and meaningful existence, the individual enters a state of stress; and when the individual faces adversity, lacks environmental (social) support, lacks coping skills and cannot solve problems, emotional problems such as tension, anxiety, depression and disappointment arise; as the individual cannot withstand extreme tension and anxiety, emotional breakdown occurs or the individual wants to seek relief, resulting in emotional imbalance, before entering a crisis state. Of course, when a person is in a state of stress and “minimal” functioning, additional, small stimuli may also upset the balance and cause him or her to enter a crisis state. A crisis is a reaction when an individual is unable to cope with the internal and external distress he or she is experiencing in the usual way. It generally occurs when an individual encounters an unavoidable and intense stressful event, and the mobilization of the available coping means fails, there is a clear acute emotional, cognitive and behavioral dysfunction, and the individual is in a state of psychological imbalance. After reawakening and readjustment, most people in crisis situations can establish a new equilibrium and get through the crisis. The duration of a crisis is generally short, no more than 6-8 weeks.
