My dentist once told me that letting go is
like losing a tooth.
When it was pulled out, you're relieved, but how many times does your tongue run over that spot that 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 leaves a gap, and sometimes you see yourself missing it terribly. It's going to take a while, and it takes time. Should you have kept the tooth? No, because it was causing you too much pain. Therefore, move on and let go.
