Think I Care nothing means nothing

I built this all brick by brick
and watched it crumble twice as quick
the more I have
the more to lose
the closer my head gets to the noose
I will disconnect myself
and never think of anything else
it doesn't matter when we're in the ground
and no one knows you were ever around
Nothing matters when you
have nothing left to lose
Build it up
tear it down
bring it back
destroy it now
