Do not miss me

Human by day,
Creature by night,
I don't know if i will win this fight.
My hair is falling,
My skin yellowing,
I'm getting sicker and sicker.
My days were numbered,
But not to plunder,
I lived a joyous life.
I love you all,
and to all of you a fairwell,
I've come to my end,
While your life just begins,
Do well while you can,
and act as though you care.
Do not miss me,
for i am always here.
