I feel a lot of pressure in class. It's embarrassing to think of the memories in class. What should I do if I am laughed at?

If you want to be happy, forget the unpleasant things. The unpleasant things are over. Stop thinking, just like a calendar. Turn it over and don't turn it back. See the blue sky and white clouds, listen to music and dance. Time will dilute everything, and there is no fire mountain that can't be crossed. A rainbow will appear after the rain clears. As long as you adjust your mentality, everything will be fine.
