Others can't enter my world, and I can't enter others' world. After living for so long, I feel that I have lived in vain, as if I have no thoughts, like a walking corpse, no.

This requires your communication skills.

You should keep your interpersonal relationship.

Happiness needs to be enjoyed, but sometimes it is easy to beat a person. When happiness suddenly comes, people are often drowned by the vortex of happiness and fall from the peak of happiness. To bear happiness is to cherish happiness instead of blindly precipitating it, just like facing an old jar of wine, you will often be drunk unconscious when you drink it at one breath, and only when you taste it slowly will you taste real mellow and sweet. Life is short, don't worry. No matter what happens, learn to think from another angle and you will feel happy. A happy life must have correct ideas, and only under the guidance of correct ideas can there be correct behavior. Correct behavior is repeated many times to form correct habits, and correct habits will shape a good character, thus creating a happy life.
