My dentist once told me that letting go is like pulling a tooth. when it was pulled out, you were relived 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 wasnt hurting you doesnt mean you didnt notice it.It leaves a gap and sometimes you see yourself missing it terribly. 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.
