first of all, you should distinguish whether others are bullying you for fun or really bullying you! If it's just making fun of you or something, you don't have to care too much. Just smile and pass. Don't care too much about everything. Everyone has self-esteem. Everyone will get hurt! If you think others are really bullying you, then you should be mature, don't make fun of your friends casually, don't boast, don't be arrogant and domineering, which will make you a stable person in the eyes of others. Do your own thing seriously, so be silent, talk less, and talk more is useless. Don't let yourself feel depressed because of a look and a word from others. You should bear it when others bully you.
