You don't have to blame them. Actually, how can I put it? The most important thing in working in a place is not how strong your ability is, nor how much money you can earn. The key is that working in a happy atmosphere is more important than anything else. They don't mean to say what they think of you or what's wrong with you. The main reason is that the people in your office are different from the environment, which has caused your estrangement. You are the head of an office. For them, you should worry about what you said or did when you were with them. After all, you don't have to care too much about them. Just do your own thing. There is no need to always think about others, and it is useless to be sad. Be brave. I'm sure they'll see. Come on! In fact, you have many friends besides them!
