How long is the end?

I screamed loud, the scare from my diagnosis, My streams of tears filled seven hundred oceans. The doctor spoke bleakly of the prognosis, His face lay bare, devoid of all emotions. Now anguish walks with glee where dreams once befriend, Hope and happiness slip out of easy reach. In their stead, despair and melancholy trend, The heartbreaking news clings to me like a leech. Cancer crept in as an unwanted Greek gift. My days grow forlorn, my strength remains hollow. It seems from my life, my soul drifts far adrift, And now in my sadness, my foes all wallow. To live or to die, my spirit must contend, Yet longevity is what my heart aspires. On God, my life's best choices firmly depend, Yet cheery news is all my soul best desires. Though death looms close, my soul refuses to bend, Capsules and tablets now govern my sorrow. From heart to mind, the fleets of my fears extend, Yet faith lights the path I've chosen to follow. My hair is gone, my body left bald and bare, How far away is this end to my torments? What weight of sorrow can this fragile soul bear? A flurry of questions this bleak news presents. How long, I wonder, is the wait for the end? Fangs of fatigue dig out more of my worries. No rays nor tablets can make any amend, As cancer cells dance gleefully in flurries.
