I'm an introvert, I'm weak at the outside, and I'm timid. Many people are watching my jokes.

This question is not difficult to answer, but it is difficult to do. It needs you to find yourself from the heart. People are most afraid of losing themselves. It doesn't really matter what others think, what matters is how you feel. You must learn to be selfish. The "selfishness" here is not really "selfishness". It means to love yourself more, so that you will be happy gradually. Only happiness can bring happiness to people around you. So there is a saying: love yourself first. Slowly understand the meaning of this, I think you will slowly and successfully free yourself.
