First, take a deep breath. Next, ask yourself if you did everything you should to make it right, apologizing was good..even if you are right and your neighbor doesn't apologize for yelling at you, you'll feel better since you apologized for yelling at her. Third, try to accept your anger and don't load guilt on top of it. You apologized, not much else you can do. The next step is to think about what triggered your anger and plan ways to prepare for it. Like, when you see your neighbor is calling, don't answer right away, but ask yourself if you're in a calm enough state to talk to her without getting angry...hope that helps!
