I've got a long road ahead of me, and nothing to back me up

I need to run away,
Far away from here.
Leave my heart and memories
And completely dissapear.

My inablity to understand
The way you come across,
Has me running for the door,
Don't worry, I'm no big loss.

Though I thought you could be the one for me,
You could never fill this void.
'Cause I've been hurt once before,
And was thoroughly destroyed.

Don't try to make me change my mind,
It's set, and I'm ready to go.
I've packed my things, I'm in my car;
Ready to hit the road.

I need this chance to get away
From all these fears and pain.
I may be strong, but all I know is,
I can't do this all again.
