I think there are many reasons. The first is the lack of education. Let's review our student life. Since we went to school, the education we received is the acquisition of knowledge. Few schools offer mental health classes. When you go to college, it will be involved, but at this time, everyone has their own outlook on life and values, which is not so easy to change. Just like building a house, the foundation is not well laid, even if the best materials are used on it, will the house be strong? Teenagers are high-risk groups with psychological problems, and no one guides and communicates correctly. Over time, it is strange that there is no problem. Secondly, in this social environment, the common misunderstanding of our society, teachers and parents is to attach importance to intellectual education and ignore moral education, physical health and mental health. Students are under great psychological pressure. When they are under great pressure, they will be depressed. If they are depressed for a long time, they may have suicidal thoughts. Moreover, from the students' own point of view, people who commit suicide have poor psychological quality. As a student, even if there is pressure, how much pressure is there? I have never experienced the ups and downs of life, and I can't bear to part with it. Even if you enter the society, you will only be eliminated. The road of life is very long. Ups and downs are the only way in life. If you can survive, you are the winner. If you can't survive, you will become a coward and you will be treated.
