People in the next unit heard the quarrel and threw things at home. When I met them, they laughed at me to my face. How can I fight back?

Ignore it. You don't say anything over and over again, ignore it, and slowly they get bored and don't answer the phone. I suggest you clarify your real inner needs and see if you can quarrel in another place in the future, such as public places, so that if you want to quarrel, you will be bound by public morality, which will indirectly reduce your anger and allow the two sides to communicate relatively rationally. This is the solution to the problem. The idea of communication can be like this: say the problem without emotion, then say your feelings, and then hope the other party will do it. The trilogy should be made clear, because we always feel bad about each other. Why can't he understand it? In fact, sometimes we can't tell ourselves clearly, especially couples, who really don't know the thinking differences caused by gender. This is also my personal experience. With this effective way of communication, my happiness in life has improved a lot. I hope I can help you solve your problems at home.

You don't need to pay attention to outsiders, that is, the people in the next unit. This is your family business. But I also advise you not to throw things around, which will also affect others. On the surface, caring about others' ridicule is actually your inner uncertainty, so you should come out slowly, don't care too much about others' comments, and gradually recognize yourself. Communication is skillful, and self-growth also requires methods and self-affirmation. good luck
