does my existence matter?

this heartsong was written by a kid who's passed away due to a congenital illness. he lived life to the fullest. mahal nak beli buku die so i amek gambar je.

some times i wonder whether anyone besides my family would care if i were to die and leave this world. (i know a few who'd be rejoicing)
would my absence be mourned upon?
would my presence be missed?
does my existence really matter?
have i done any good in this world?
have i actually helped anyone at all?
will i ever get married? [eh tersesat plak that question]
i wonder...

for now, i better go back to my study group :p
