My pen and paper

A pen and is,
your window to my world.
with this pen i write,
all my secret delights.

and with this paper,
is my knife,
to write down all my fright.

on this paper i will write,
all the pain i have inside.
i have to write,
if i don't write i will die...

i will die and you won't know,
what caused this girl to go.
i know you think you know,
but you have no idea what you don't.
