"If this isn't the end, I don't know what is."

Not quite....at least hopefully not. However, the world has seen many interpreted end-of-the-world events. The city of Venice was founded on escaping the "end' when Attila the Hun conquered much of Europe. His hoards of horseback fighting warriors was thought to be Armageddon and the devil himself. To escape this madness and prevent Attila's horses-from-hell reaching them, people fled to the marshes and built a dwelling therein. This became Venice. At that time, people believed the end of the world was at hand.

Best thing to do is wake up in the morning.... the moment your eyes open and witness the new day, thank God you are spared to live another day. Getting up in the morning focus on it and live it as if it is your last day. At night when you go to bed, give thanks to God. Pray that you may wake up to another joyous day.

This is essentially living a day at a time. Don't worry or attempt to interpret the future.
