Being ignored by others since childhood, what will become when you grow up?

I'm not confident, sometimes I'm motivated to do things, but in the end I really feel really bad because of a sentence or two others said. Without confidence in yourself, it is easy to get lost. I always feel that I have done nothing. Generally speaking, people who are more confident and better than themselves are more likely to lose confidence and feel inferior. Sometimes, he loves to brag, mainly because of his inferiority complex. I hope I can satisfy my image of being very capable in others' hearts through some exaggerated things, because I have never been recognized by others, and I can also have family factors. My parents have something to do with the way they were raised. They like to suppress their children. They always think that other people's children are good and their own children are poor, and then they look down on them. Over time, people must have shadows in their hearts, and over time they will form inferiority complex. I still want to say here that everyone needs encouragement, especially.
