What should I do if I was always laughed at as a child?

You don't have to force yourself to change anything, no matter what others think of you, don't care too much. There are countless eyes from the outside world. It is very tiring to live under the approval or attention of others. Confidence that needs to be recognized is not true confidence, it will not follow you all your life. If you want to make it clear that you want to change your present situation, you can, but you must remember that change is not for others, but for yourself, and work hard for yourself, not for others. Everyone is not born perfect, but most people still live happily. I hope you can find your own bright spot and live happily every day.
