Hard Shell

It seems like a hard shell, My body has been carrying, What is the age of this shell? Will it become like it used to be again? Or will it keep growing its mighty fangs? I ponder... But I believe it will go away some day, And reshape my body the way it used to be, This shell aghasts me, Sometimes conquers me, Other times telling me it’ll go away, Hush! Will the day come when it departs, I will love life like I used to once again.
