My bones have become filled
     to the brim with lead
until each step I take
     is so labored
     I can barely make another.
I am exhausted
     to my very core
And I'm expending
     every ounce of my energy
     simply attempting
     to hold my eyelids up.
I can't anymore, I'm sorry.
I just can't, I'm too tired,
I'm going to sleep now,
that deep, restful sleep
     from which one doesn't awake.
