I have a terrible stomachache in class, but I dare not tell my teachers and classmates. What should I do?

You must overcome shyness first,

If there is anything else in the future,

And when you go out into society, you have to deal with colleagues and leaders.

So say what you want to say bravely,

In addition, cover your navel with your palm,

This can prevent colds,

Put your hands up and tell the teacher quickly.
