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 you tongue run 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 leave a gap and sometimes you see yourself missing it terribly. It;s going to take a while, but it takes times. Should you have kept the tooth? No, because it was causing you so much pain. Therefore, move on and let go.
