Looks are given by parents. There is no need to feel that you are ugly. It is natural to be treated unfairly. Everyone is unique. You should make the most beautiful fireworks in your own world. Don't think about why you don't like others. Such inferiority will make you more and more negative, so that you will have some other negative emotions.
Because there are many reasons for inferiority, most of them are not from themselves, but mostly from external factors. There may be some ordinary-looking children, or good-looking children, who become less confident and pretend to be themselves because of some outside remarks, which leads them to really become the people they say they are.
Inferiority is nothing. You can feel inferior or not, but I want you to know that when you feel inferior because of your appearance, some people may be born imperfect and unable to live a normal life. When they are still optimistic about the world, what reason do you have to say that you are not confident because of their looks?
I am also an inferior child. No matter how much I pretend, I can't hide my inner negativity. I sometimes want to change and feel that the world is unfair to me. But when I see some people who struggle for their lives and dreams, what reason do I have to feel inferior because of their innate appearance?
Since there is no way to change the outside, beat it psychologically!
