I think the words I was trying to remember were "I am the heart that you call home" and "I have written pages upon pages trying to rid you of my bones". It didn't work, by the way. I didn't really want it to.
I went home and have been listening to Decemberists albums ever since. Once, I thought I had forgotten what I was looking for, and another time questioned if I would know the significance of the song to what I was feeling a few days ago. Luckily, it all came back when the song finally played. It was disarmingly beautiful and hope snuck up on me in a way I didn't think was possible anymore.
