Social fear has become an increasingly common phenomenon in contemporary society. The word social phobia only appeared in recent years, which is social phobia. Many people show that they have such a problem, that is, they will have fear and rejection in the face of various social interactions. They would rather be alone than associate with others. They never want to bother the second person when they can solve their own problems, and try to avoid unnecessary social interaction. This is a typical symptom of social fear. In fact, social fear is not a big deal, it is a psychological obstacle, which is related to the development of the whole society. On the one hand, it is related to social pressure and the pace of life. With the development of modern economy and the accelerated pace of life, most people are exhausted and busy with survival. The pressure of work and life alone is already overwhelming. Therefore, after work, many people have no energy to socialize. They prefer to stay at home, enjoy a moment of leisure time, and find some peace in this crazy society. So this is why many people don't want to eat at the same time and make friends with strangers. Another important reason is the emergence of the Internet. Although the emergence of the Internet has facilitated people's lives and accelerated the communication between people, it has also alienated the relationship between people to some extent. Mobile phones and computers are within reach in our daily life. They help us get entertainment and broaden our horizons. Many people in life have become accustomed to the virtual cyberspace in mobile phones and computers, and are unfamiliar with and even afraid of face-to-face communication in real life. Communication between virtual networks is more selective and decisive, while social interaction in real life is not. Many times, the social situation depends on the environment we live in, and the people we get along with are not determined by us, so many people are less and less accustomed to face-to-face communication and will become more strangers over time. Nowadays, young people are more open-minded and independent. They don't blindly follow fixed social customs. For example, when we meet neighbors or acquaintances on the road, we should say hello. More and more young people choose to turn a blind eye. Maybe they are not really rude, but they really don't know how to say it, or they can't say it in their hearts. They are also very entangled and struggling. Social fear still needs us to overcome more, find out the reasons of our social fear and try to overcome it.
