Why do I have nothing to say to anyone?

Hello, everyone is unique. Some people prefer to socialize and talk endlessly, but some people don't like socializing very much and prefer to think about some problems by themselves. Each has its own characteristics, which can't be said to be good or bad, but our society advocates extroversion too much, so some people who don't fit in with others think this is a shortcoming. In fact, on the contrary, introverts tend to be more introspective and pay more attention to the depth of thought.

It's important to accept your personality and uniqueness, and you will feel much more comfortable.

On the other hand, judging from what you gave, it's not that you don't want to associate with people, but that you don't express yourself well enough. I feel that something inside you has been suppressed, and some negative emotions have not been handled well, so I am somewhat isolated from my feelings. Just try it. When you feel good or bad, tell your true feelings. When you can express yourself, your heart will open. It doesn't matter how much you express it.

I wish you happiness!
