Our landlord hared us until we moved out.?

You are justly angry. You and your family were treated very badly. She is shooting herself in the foot. Every turnover costs a landlord cleanup costs, advertising, and sometimes a vacancy. She has some serious personal problems, that go beyond her behavior as a landlady. Do not sue her. You would lose money on the action. Bite your tongue, say a prayer, and turn your back on the past. Then move on. Happy thanksgiving.
