I hope this song never has to resonate personally with you. But if it does, I think it expresses the drama of that turning point where the overwhelming emptiness of loss begins to ebb, you are in over your head but your toe touches bottom, and you start to think you might see another dawn.
This is a song for someone whose relationship has ended after a long time, not a year or two. Strings don't scale for you up into infinity like in this song's gargantuan ending unless there are some serious stakes.
From its elegiac verses to its choruses of meditative shockwaves, to that rebirth of an ending, this is an unbelievable song.
