I know this sounds cliche (and rightly so), but it is, nonetheless, true: This is not the end; it is only the beginning.
Okay, so, as it is, it's only partly true. What it should really say is this: You're at the end of one journey and the beginning of another. And so shall it always be.
Though pain, sadness and trials may come, embrace life's challenges and persevere to the end; you will find such things help cultivate and strengthen the complexity and uniqueness of your character.
Oh, and don't forget to have a little fun (and some R&R) along the way.
May God be with you as you journey on.
