How did you do it?

I’m not normal
But you made every broken piece fit
I’m not open
But you walked though every wall to hold me without reservations
I’m not happy
But you made every moment worthwhile
I’m not sad you’ve moved on
You deserve true happiness
and I guess that wasn’t me
But I’m left wondering how you did what you do
And how or if I’ll ever find anyone else who can
How did you make a dead man feel?
