Sam's POV. That year he spent alone must've been tough...

I’ve got no one, I don’t know where to go 
Dean, I tried, but I’m so alone

Dean, I’m sorry it couldn’t go the way we planned, yeah, 
I mean, I know you’re stuck in purgatory and I’m so sorry I didn’t carry on, no 
But you left me all alone, you’re with Cas, and I have got no home 
I mean, what am I supposed to do without you? I’m so lost I just can’t do this, no

I thought if I just [bad word]  stop caring if I died 
I could get up, get out, never said I didn’t try to do this alone 
But it’s just too much and it’s just too hard, 
Without you Dean, and without dad 
To fight when I got nothing to fight for

I should’ve saved you, I should’ve saved you 
If I’d have known you [bad word] back to me, 
I would’ve never abandoned my family

I prayed to God to return you to me 
But then I moved on, moved on from your memory 
I built a life without you there 
Never before had I been so scared 
Without you

I had no one, I had nowhere to go 
But now you’re back, Dean
