The juggernaut of time

How do you bring yourself to accept loss? I've struggled rather avoided this topic for most of my life. Now I'm forced to face it. I suppose when it's sudden you are thrown into it but when you are given a timeline then it's an eventuality you must look on to every day. Time marches on, it keeps going forward like a juggernaut and brings the inevitable closer and closer every day. And I must face this oncoming juggernaut each day now. The realisation that no matter what I do I cannot change the eventual outcome puts into perspective just how powerless we are infront of fate and destiny.
