Its main characteristic is the fear of attention from others, so it appears unnatural, blushing, dizzy, headache, panic, shortness of breath or no place to be, so it appears avoidance, unwilling to communicate with others, afraid to go and look at others. It is very important to think about what you think when others look at you, or when you look at others’ eyes, because your thoughts determine your emotions.
