What if I can't integrate into the group?

I have the same problem as you, but it has been solved recently.

Actually, it's very simple. It's just a trick. When you get it, all the nervousness, shyness, anxiety and embarrassment disappear. The trick is: don't take yourself too seriously, don't care too much about yourself. You know, when you are with everyone, you will feel that everyone is paying attention to you and watching you, and they will laugh at you when you make a fool of yourself, but all this is your own imagination, not true. In fact, no one will pay attention to what you say or do.

When you are in a crowd, you can try to observe carefully what everyone is doing, what topics they are talking about, what rules they are playing, who wins your applause and who loses, and comfort him. When listening to others talk about their own affairs, you can carefully understand their feelings, whether they are happy, sad or want people to pay attention. When you pay enough attention to others, you will forget yourself. When you forget yourself, you really fit in.
