My heart in disarray!

Whats behind this mask
whats beyond these walls
whats it really like
when my defense falls

no one has ever known
no ones attempted to see
what its really like
to live a day as me

I've always been the one
who people do pass up
nothing really special
I'm a half empty cup

but you are just out side
chiseling away
you're trying to get in
and watch my defense decay

But I'm playing hard to get
hoping you'll walk away
so you wont have to see
my heart in disarray
