"S is for Susan who perished of fits"
Recollecting now on a certain time line, where children having adult sickness were implausible. For on how aging and immune system works against the qualms other worry about. Those stages found in elderly people, are just a rare thing for children. For someone like Susan, she was known as one those uncommon moments, where it must be noticed that life, is just a faction of trouble.
Having a child trapped inner wise, as an adult, having just time be her own enemy. Susan would have those cold shivers, high fevers, dried mouth, stiff limbs, and such else. Where at first moments, getting to one place is just a challenge. Eating things must be chosen with caution, or the fits will catch on her, and likely end her quicker.
Susan is that fear, a walking fear of being trapped in own body. Little poor Susan, at most times, is just waiting for her body to give up, and let the will take her away. That's all it is to Susan than most kids. Who get see adulthood, but compare to Susan that's her dream at times, what would be like for her, to be a young lady than a young child. To have that one wish, at the tip of her fingers, could be taken away from her and there is nothing little Susan can do about it.
As far as the medicine of her can do, it can weaken the shiver of fits, but to just save her altogether, is just out of the question. That's all it there, there is nothing, Susan is just a life trying to live, even though at the end of it all, won't mean a damn thing. Yet, Susan is still a child, so what does she know on how little time she has. Susan got to at least try.
Susan is a child's death, that is very simple and to the point, that it is hard to think, of how else this could end for her. This sickness that is too strong of her time, because of that, she'll die. End of story there for her. But there is one good thing for her, no matter how sad it could be is this; she's going to die no younger than her fellow classmates, why not and try live for the most of it.
Susan is one those children that knows her fit, so until it comes, she'll live it up. Do what she wants and be happy while she can, until to the sad end comes. To that, for then Susan is going to live, until finding a way to rest in peace, until the fits become too much. And dying alone, because it was how she wanted it, even for most wouldn't.
It works out for her, because this was Susan's life that she had a little control of it, and used it. Compare to most kids, which is saying something, even though like others, is still sad. But again, it is her ending.
