Why is this my life

Cancer. That's all the cam end a life,all you need,to die,nothing can cure it,nothing at all. So when Lydia Evens finds out she has it she's devastated,of course this ends her chances of ever being able to go to college to play the cello,she can't travel with the sickness,and it's even hard to get out of bed without loosing her breath,but when Eyeless Jack comes for her,he feels pity for the young frail girl,will she die at his hand or from the cancer?
