Building a wall

You wonder why, why I don't open
I been their, so much hopen
Much damage, I built a wall
Came crashing, you should've seen what I saw
Letting one person, have so much trust
Ended bad, I com bust
So you wonder why, why I don't open
You should see, how much I've been copen
Getting through the day is hard enough
But seeing your face, is way to tough
You let me down, you threw me away
Because of you, I wanna die, each and everyday
