Why do I always feel like others look down on me and am afraid of being laughed at when I do anything? Is it psychological reason?

This is a sign of lack of self-confidence and a lack of opportunities to be communicated. I feel that the poster should be a relatively passive person.

I also had this experience when I was in school. I always felt that people around me looked down on me. Because my academic performance was poor at that time, I worked overtime every day to review my homework, find out my weak links, and then work on them one by one. After half a year, my grades improved and I was admitted to university. Everyone was right. I was amazed.

But this is only one aspect. I give this example to tell the poster that no matter whether you are studying or working, you must do your own things well and try not to let others find faults. That's half the battle.

Sorry when there are many people.

It feels like the poster may be a bit of a homebody. When you have nothing to do, you should go out and get together with friends more often, chat, change your personality, make yourself more cheerful, and you will no longer be embarrassed.

When I was in college, I didn’t dare to talk to girls at first because I was always nervous. By chance, I joined a section on literature and art organized by the student union, and I happened to be selected for it. There are a lot of unknown people there, and there are a lot of girls, so I will definitely be nervous at first. At that time, there was a young man who was very kind to me. He always took me to eat and drink whenever I had nothing to do. As time passed, I found that I became more cheerful and made many friends of the opposite sex. This was a change in myself.

I hope the poster can overcome his psychological barriers as soon as possible. Everything is very simple, as long as you are willing to do it.
