What should I do if I am lonely?

Then this should be your problem. You can't adapt society to you, you have to adapt to society. No one in the world can think like you. You can't feel that you don't have the same language as them. Shopping and playing together don't need to have a common language. You can have dinner with your colleagues after work. You can talk nonsense, say entertainment news, what is popular, and speak slowly. Don't exclude others. It doesn't need too many languages to ask colleagues to go shopping and watch movies. Hate is simple. There are many kinds of friends. Playing basketball is a friend. Eating is a kind of friend. Drinking is another kind. Just for fun. How do you know you can't play? Change yourself first, talk more, or talk nonsense! A talkative person must have friends!
