Ok so I am having a breakdown. I don't know how many people have said this before but if Angel with the shotgun is a song written by Cas for Dean, Angel like you by Miley Cyrus is a song written by Dean for Cas. He is his angel but he doesn't think he deserves him. He knows he can't be with the angel because he is too pure for him and anytime he looks at himself he just sees a sum of his mistakes, his worst nightmares staring back at him, everything that's wrong with world.
"I'm everything they said I would be" - A killer, Daddy's blunt instrument, nothing if not living for others. Who am I if not just a screw up?
"the more that you give the less I need" - You gave everything for me. You gave up heaven for me and I don't want anything now because I can't see it. I can't see you falling to my level because that's what this is, A fall. I'm nothing. Don't come near me.
"I brought you down to your knees...Misery loves company" - I brought you down, stripped you off everything holy and broke you. I loved you, couldn't stay without you, asked you, needed you... I needed you and that company, me...ruined you.
"It's not your fault I ruin everything It's not your fault I can't be what you need " - Everything I touch, breaks. When you touched me, you lost everything. You try to save me and I push and push and push because I don't deserve to be saved. I don't. It's not your fault. I wish I could give but I am hollow, trying to remember what it feels to have a heartbeat. I don't know how to be what you deserve.
"Angels like you don't fly down hell with me"
I...I am sorry I am having a breakdown.
