From your description, I think you may be pessimistic about some social status quo. Generally speaking, society is complex. There are good people and bad people, and making friends is the same. You will also make good friends and some bad friends. Make friends in society, take care of yourself, and don't reveal too much personal information. It is not ruled out that some bad friends will stab you in the back. Therefore, in this complex society, we should try our best to be ourselves, and at the same time, we should also deal with various external challenges.
