" You can't metabolize the loss. It is in the cells of your face, your chest, behind the eyes, in the twists of your gut. Muscle, sinew, bone. It is all of you. When you walk you propel it forward....Then it sits with you. The pain puts its arm over your shoulders. It is your closest friend, steadfast. And at night you can't bear to hear your own breath, unaccompanied by another. And underneath the big stillness like a score, is the roaring of the cataract of everything being and being torn away. Then, the pain is lying beside your side, close. Does not bother you with the sound even of breathing. "
