Most of us do just about the best we know how to do. And, even as little children, we assume great responsibility for our situation. Recognize the truth. If you feel true guilt, acknowledge your mistake, learn from it, and forgive yourself. In either situation, forgive and move on.
Anger is associated with fear and loss.
It is frequently experienced when we haven't previously expressed our feelings. The more we look at the sources of our anger, the closer we will come to reducing our fears and increasing our understanding. As we understand, we gain acceptance. With acceptance, we can begin to forgive. As we do this, the feeling of being angry ends.
