According to Freud’s “Inhibition, Symptoms and Anxiety” in the theory of anxiety, anxiety is divided into three types, reality anxiety, moral anxiety, and neurotic anxiety. 1, reality anxiety Fear of crashing when flying, fear of being burgled when alone at home, insecurity in a strange city, have you ever had these feelings? When we worry that some danger will happen in the external world, the brain will send us a signal to remind us and alert us, this signal is reality anxiety. 2, moral anxiety Have you ever had some immoral thoughts? Have you ever regretted having done something wrong? We will feel guilty and ashamed for this, why exactly? We have been taught by our parents, teachers and society what to do and what not to do since we were young. They are our “moral arbiters”, once we “do something wrong”, we will be punished, and over time, the content of these teachings becomes the morality in our hearts. Once we do, or even try to do, something unethical, the brain punishes itself with guilt and shame. We hate, or even well afraid of guilt and shame, two extremely negative emotions, in order to avoid the arrival of punishment, the brain will send us anxiety signals to remind us, this is moral anxiety. 3, nervous anxiety Have you ever had inexplicable anxiety? You can’t find the source but it lingers, and you don’t even know what you’re anxious about? Neuroanxiety is an upgraded version of reality anxiety, but it is hidden so deep that we simply realize that everyone has a strong desire and fear of something inside. (Love, money, sex, power, drugs, etc.) When these desires and fears are released in large quantities, it is easy to bring us to the verge of a breakdown, at which point the brain sends out signals that are neuroanxiety signals. Anxiety is not a disease Many people hate anxiety and think it is as bad as anything else. In fact, anxiety is not the root cause of many of our illnesses. In many cases it is the struggle and confrontation to get rid of anxiety that leads to psychological problems: when we adopt compulsive behaviors to reduce anxiety, we form obsessive-compulsive disorder; when we adopt doing it later to reduce anxiety, we form procrastination. Anxiety is a universal emotional currency generated by the mind, arising from the mind’s imagination of the future, and the fear of the future we can all display through feelings of anxiety. As mentioned above, anxiety is a reminder to the brain, a defense mechanism, and research has shown that a certain level of anxiety can make people perform better.
