What should I do if I can't stand being laughed at?

According to your description, I feel that you are usually alone, which is a bit strange for people who like groups, so I laugh at you a little. There is no need to care about these people. Mediocre brainless people like a bunch of people, who have neither ideas nor personalities. Their so-called ridicule is sometimes intentional, and the essence of their hearts is jealousy (for example, when I was in the third year of high school, the girl who was isolated and slandered by the girls in the class was actually the best girl in the class-excellent in English, ancient prose and writing); Sometimes, it is because they have no brains that people who are different from them are ridiculous. Try to ignore these people at ordinary times, so as not to waste your time and energy and do what you should do. Don't show anger in front of them, or they will be happy and excited. If you ignore them, they will be more honest if they are bored. Besides, it can be seen that what you are after is true friendship. These girls are in groups of three or five, some of them are intimate on the surface and secretly undermine each other. I've seen a lot. It is better to be alone than to be so hypocritical.
