My aunt is Vietnamese and she won't leave me alone. She likes to yell at me for no reason, and she also slaps me when I give my opinion. She punishes me every week, is she crazy? She won't listen to me, so I can't talk to her. How can I make her leave me alone?

I have tried talking to another relative, but when my aunt found out, she punished me for months because of this. So I can't talk to anyone.
