Educate yourself, people get angry, frustrated, scared, defensive, anxious, when they have such a rigid way of understanding. and nobody teaches you this stuff. It takes a lot of time, it will be tough, experiences will help. I can tell you are smart by recognizing how these behavior effect you and seeking help, a lot of people don't get past this step. Face your fears, get to know them, how old are you? I don't want you to get specific if you don't' want, but what kind of incident happened?
