What should I do if I lack self-confidence and give people a feeling that I am stupid and can't get on the table?

Then you can only find a job that suits you and you don't need to rush to the front line. When I was in junior high school, I got depression because of lack of self-confidence. When I was serious, I hurt myself. Now I feel a little stronger at the age of 25, and the doctor's advice is to live an ordinary life. Don't think about those jobs that pursue high salary and dare to challenge. Be an honest clerk or editor, or simply do manual work. As for starting a family, it is of course best to meet the right one. If not, I suggest giving up this idea, which will only add a lot of trouble and delay others. Or you can look for ways to cultivate self-confidence (I have tried many times, but it didn't work). In a word, I think self-confidence is cultivated when I was a child. 13- 15 years old, it is not easy to make up for it.
