Everyone has anxiety and anxiety symptoms. If we draw anxiety into a continuous spectrum, one end is no anxiety, the other end is severe symptomatic anxiety, and anxiety is in the middle. For example, office workers worry about whether they are doing well at work or whether students are doing well on exams when they go to school, and so on, all belong to anxiety. Anxiety in the appropriate range can promote learning and work and improve efficiency, but if anxiety has become so serious that it affects learning and life, learning, work and life can not be carried out, then the anxiety symptoms are already very serious. If anxiety is so severe that it produces physical conditions, such as panic attacks, palpitations, or affects normal work during the day, and there is no way to work or live, and it also produces a painful experience, then the disease is formed, and it is necessary to seek medical help.
