Hold on or Let go

It is easier to say na you will let go because you are tired of pain and you are hurting but in your heat you know thay you will still hold on until you can. Letting go means moving on while holding on means waiting. Will you wait for something that you know there is no chance at the present, maybe on the future but the uncertainty is still there would you risk your time for that or would you just let go and move on while keeping the love you have for that person
