My nephew said to me, "You are fat and ugly. You look disgusting. You are disgusting. I don't like you. This is my home. You are not welcome." What should I do?

Your nephew should still be a child. Sometimes people say that children talk nonsense, and sometimes people say that children should not care too much about what they say. There is some truth in this. The child speaks without considering the consequences. He can say whatever he wants now. You should argue with him. One is that others think you are making a mountain out of a molehill, and the other is that others will really think about whether he is right or not. These are not good for you.

You can ignore him and face up to your own shortcomings, and really improving yourself is the real solution to the problem.
