Y do I have to be sick?

The last week has been full of coughs, sniffles, and aching bones. As the seasons change, fall comes, leaves change and every year without fail I am miserable, caught between summer and fall and as sick as can be. I found myself laying on the floor looking up at the ceiling trying to remember the last time I wasn't sick, and as my head throbbed and nose as red as can be it's hard to remember that day. I closed my eyes and tried to remember what it felt like to feel normal. As I look out my apartment window up to the mountain, it expresses my feelings so well in just one letter, Y?
