How can I change my perception?

Memories may bring psychological pressure, but this is not the main thing, first of all, you have to figure out, many people have social phobia, that is to say, not willing to socialize with strangers, even if socialize is not open, I am such a person, this is not any autism, but lack of self-confidence, but then again, I have a friend who has a pretty good career, and he feels the same way, it can be accurate to say that any person It's like that, it's an innate human fear, just like how we're still afraid of ghosts even though we've never seen one, it's a fear of things. Since though, many people can't look at this properly, and afterward they feel more and more incompetent and inferior, so they develop autism or other mental disorders. I'll tell you the truest of words: people are fearful because they believe, and wild because they are ignorant. Finding a balance between awe and fear is a technique of life.
