Kacey Musgraves - Deeper Well (song) release date?

About the single "Kacey Musgraves - Deeper Well":

So I'm sayin' goodbye to the people
That I feel are real good at wastin' my time
No regrets, baby, I just think that maybe
You go your way and I'll go mine
It's been a real good time
But you got dark energy, somethin' I can't unsee
And I've got to take care of myself
I found a deeper well..
