Another form of bargaining, which many people do, and she did too, is to replay the final painful moments over and over in her head as if by doing so she could eventually create a different outcome. It is natural to replay in your mind the details. Deep in your heart you know what is true. Your mouth speaks the words, “My cat has died,” but you still don’t really want to believe it. You go over and over and over it in your mind. Your heart replays the scene for you for the express purpose of teaching you to accept what has happened. While your heart tries to “rewire” your mind to accept it, your mind keeps looking for a different answer. It doesn’t like the truth. Like anything else, when you hear it enough, you finally accept that it is true.
