My dentist once told me that letting go is like pulling a tooth.
When it was pulled out, you’re 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 did not notice it. It leaves a gap and sometimes you see yourself missing it terribly. It’s 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.
