Let you and your family cool down. They probably just became aggressive because of the disagreements. Try not to clash with them too much. If they said something you disagree with, let it go because the arguements and tensions would escalate. I used to feel the same way about my own family years before. But then I stopped talking back even if I knew they were wrong. Families in reality is nothing like the perfect families you see on t.v. But don't let the reality of your family make you feel sad and hopeless. If you let them cool down (and yourself as well), eventually they would think over what they said and did to you. Perhaps then, they would realize how wrong they are.
