My dentist once told me that letting go is like pulling a tooth.
When it was pulled out, you are relieved, but how many times
does your tongue run itself over the spot where the tooth once was?
Probably a hundred times a day.
Just because it was not hurting you doesn't mean you didn't notice it.
It leaves a gap and sometimes you see yourself missing it terribly.
It is going to take a while, but it takes time.
Should you have kept the tooth?
No, because it was causing you so much pain.
Therefore, move on and let go.
