Letting go is like pulling a tooth. When it was pulled out, You were relieved, but how many times does your tongue run itself over the spot where the tooth was ? Probably a hundred times a day. Just because it wasn't hurting you doesn't mean you didn't notice it. It leaves a gap and sometimes you see yourself missing it terrible. Its going to take a while but it takes time. Should you have kept the tooth? No, because it was causing you too much pain. Therefore, Move on and let go.
