Here’s a crazy idea. Maybe the next time they fight, you go up to them and just start screaming and holding your hands over your ears. This way, they can’t hear themselves fight, and you draw attention to yourself. Maybe they will wonder what you are doing.
If they think you can’t understand, then perhaps this will demonstrate that you truly don’t understand (and this may true). But it demonstrates in a way that doesn’t attack them that much that you can’t stand it.
Now they may or probably will get angry with you. Perhaps they will get angry enough to try to hit you, but that may be better than having them go at each other. It’s a risky approach, but it might work once. It might jolt them out of their habits.
Since you’re Asian, I can’t suggest that you have them go to therapy. Asians tend not to believe in mental health and therapy. It brings shame to the families. That’s the other thing that screaming does. It might make them think about the family, since by screaming, you risk bringing shame on the family if friends and neighbors hear. In other words, you side track the issues.
But you’re really stuck unless you are willing to take risks because your culture does not admit to the existence of family problems. The police ignore them. Your father is right. Your mother is not doing her duty by obeying his every whim and wish. This is powerful stuff that you are up against.
Traditionally, where possible (and it is different in every culture in Asia), it is sometimes possible for women to go back home to their parents. But again, it depends. It’s different in China (possible) than Tibet (impossible) and different still in Bali or Vietnam. It depends on the tribes your people come from and whether you live in an urban or rural area and what kind of education you’ve had and whether you’ve spent time in the US and so many other things.
Sometimes, you have to do the unthinkable and leave. You risk being cut off from your family. You risk being seen as a whore. But it may be better in the long run than staying in that toxic environment, which is giving you stress and will cause psychological problems for you for a long time in the future—problems you are unlikely to get help for unless the culture changes rapidly, or you move to the US. Even if you did come to the US, you’d need a therapist with a strong knowledge of your culture, and they may not exist.
So asking us for help is not likely to get you much good advice because most of us don’t understand what your life is like. All we can say is that we are sorry you are going through this and wish you luck. I think it is still true you can do little, so you must protect yourself. You must learn that you are not at fault. Your parents are bringing shame on your family, yes, but you don’t have to take that shame. You need to learn how not to take it on, if you are to avoid a lot of shame problems in the future.
