Here’s my take (as a therapist): There’s no reason to stress about anything tonight.
There’s nothing more you can do unless you live in a state where the polls are still open and you haven’t voted. If so – go vote.
So enjoy your evening and get a good night’s rest knowing that the moon will still glow and the stars will still twinkle. In the morning it will be a new day – what you know for sure is that the sun will still come up, the wind will still blow, the waves will still crash on shore.
Tonight there’s nothing more to be done. So there’s nothing to do except enjoy life.
