questions that keep my neck stiff

is it possible
to love someone
so much that
you can't love them.
and to think
about them
so much that
you can't think
at all about
them or anything.
and even if
you know what
you should do
can you ever
do it if you
don't really want
to do what you
know is right.
and can someone
be so selfish
that he doesn't
even care about
himself at all.
if pleasing someone
else is all you want
is it ever possible
to please yourself.
can i ever really
want anything outside
of my own.
