The Monster Under The Bed

People have called me brave and strong but the truth is I am a coward. I live every day/night as if the monster will get me. It has already taken my uterus and ovaries, my spleen, a section of my liver (at least that organ fights back), two sections of my spine (one replaced with synthetic and the other by donor), and most recently it has set its sight on lungs. So I am not brave or strong but I am stubborn.
