"Four Word Letter" lyrics

I wrote a four word letter
Though I'd lived I hadn't been alive
You held my hem but I traveled blind
Thought I'd sold my soul for something better
The rain came down, it wet my eyes
I didn't mind
It's not me that you've missed
You heard me when I cried
"You've seen you've loved a side of me that died"
I remember sunshine
And you were mine
It's still a little cloudy but there's no rain in sight
You were mine
