Over too soon

I know I've got time
I can't waste it all right now
I know it's not mine
I'll make it up some way some how

What if this tunnels a cave and
I have to sit and figure on my own
What if all this never makes sense
Trick myself into believing I belong
This whole time I've been wrong

I know I can't stop feeling this way
who am I to blame for not being able to escape
Break me down.
