Why sometimes, I habitually like to be self-enclosed?

Hello, because your question gives less information. So the answer is broader.

In fact, self-isolation is not completely bad. The mind needs to be protected. If you are in a threatened state, your mind is self-enclosed. This is to "arm the mind" and give it a shelter.

At other times, we will find that at the moment when the mind is not threatened, we will unconsciously tend to be self-enclosed. If this happens, we can actually consider whether there are situations in our lives that make us feel hurt, so when similar situations occur, our minds will automatically "close themselves."

Then, when you habitually like to be self-enclosed, you should consider what kind of personality foundation you have laid for yourself from your childhood growth environment. People who like to be alone, or people who are insecure, naturally prefer to be self-enclosed. This is not necessarily a bad thing. Every personality has its own advantages. For example, people who know how to close themselves have a clearer sense of boundaries than those who don't.

I wonder if you are satisfied with the answer to this question. I'm just talking in general terms here. Psychology is very interesting and extensive. Psychology can make people look at problems from multiple angles, so can the problem of self-isolation.
