How you view death impacts how you live life. You now have a feeling shared and contemplated by all of humankind before you, and all the humankind after you. This is the human condition.
Embrace it, come to terms with it, choose to live today and enjoy rather than worrying about that which you have no control over.
Those words are very easy to type but much harder to live.
Best of luck.
They totally feel it to be true, and they’ve been told their feelings are more valuable and true than actual facts.
