Is introversion a deformed personality? I am such a person, living in pain.

Introversion is not a deformed personality, but another independent personality opposite to extroversion! Extroverts are active, like to communicate with others and are good at communication. Introverts are quiet, like to be alone, unsociable and don't like to communicate with others. Because they are not good at making friends with others, they are more likely to get mental illness. Some introverts yearn for extroverts and envy them for having many friends and being sociable. In fact, they also have troubles. They are afraid of loneliness and being alone, which will make them crazy and have no energy! Introverts don't do this! Every personality has its own characteristics and shortcomings. I think you should go out for a drink and chat with your friends more, and your mood will be better!
