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

As soon as I saw this question, I thought of Li's birthday speech meeting. He said: people are social animals and live for others. I can't be myself, and I don't want to be an obstacle to others. Only by making others happy can I live healthily in gold and silver. What impressed me most about these words was the "OK" attitude. Nothing is important, anything is ok. But for me, the reason why I am unhappy but make others happy is inferiority and loneliness. I don't want to live alone in the world. You can't get a sense of security from your parents, but you want to gain it by pleasing others. Then, before you know it, you will transition to a state where nothing Li Dan said is important. But we just pretend to be like this, because no one cares about your frustration in this era, and people will always stay away from those who have negative emotions. So, what can you do except pretend to be happy? ?
