Locked In

There are four walls around me
Holding me in
As sure and steady as any prison
Escape is on my mind
But I inflicted them upon myself

There are four walls around me
Growing taller
Closing steadily in
Screaming, I try to break free
But I locked the door myself

There are four walls around me
They will crush me with their strength
Binding me forever
Keeping me here for eternity
But I cursed my body, my mind, myself
