OH MY GOD SHE IS SO PERFECT HOW CAN SHE BE REAL. 

This song literally turned me into a sobbing mess, it's just so... beautiful. 

And her twitter update on the song:

Three years, she's had this song written for three years. She kept it for three years, that's how much it means to her. 

Ugh the meaning behind this is just so great and sweet and her voice is so pretty and she sings so emotionally and and and..... I'm just gonna shut up and listen to it again.
