Let's go!

Your life lives half a nation away, my heart hurts so.
I believe letting you go was the biggest mistake of my life.
What did I do?
Alone and confused.
What can I say?
What can I do?

I'm heading the wrong way home. Knowing alone is alone.
It's just too difficult to be just me instead of we.
What did I do?
Alone and confused.
What can I say?
Nothing.

I don't know where to begin since you left me for him.
I don't know where to begin and you left me for him. (What did I
do?)
I don't want to start again, and I can't be your friend. (What
can I say?)
I don't know where to begin since you left me for him.
