What is the mentality of people who are unhappy but tell jokes to please others?

I am unhappy, but I tell jokes to please others: 1. I know the pain of unhappiness, and I am hopeless. I don't want others to make the same mistakes, so I try to please others with humor. 2. bad psychology. With the goal of pleasing others, as long as you see others happy, you will be comfortable. 3. Try to infect yourself through other people's happiness. If you are unhappy, you may be saved. As long as the people around you are happy and create a happy atmosphere for them, you will be happy one day. Personally, I think it is better to please others than to enrich myself. Only with a rich heart, everything is not finished ...?
