I am always laughed at by people who think I am important. What should I do?

Learn to control your emotions. When others laugh at you, although you can't blindly accept others' ridicule, you should learn to protect yourself. If you are angry, it means you care. It's just an uncertainty about myself. In the face of others' ridicule, you can laugh it off and make yourself strong enough, so that you will be hurt less and your shortcomings can be corrected slowly. The best way is to show your strengths to the fullest, and your weaknesses will be gradually improved.
