the worst feeling in the world could be debatable
I believe it's trying to change something
you have the full drive and desire to
but
it's not in your control
maybe parts but not all
or knowing
something
one choice
would make someone you love happier
and that's all you want
but they won't choose it
and you know they know what's right
but you can't do anything but hope
and pray
and have faith
they will
and if they don't
try to remind yourself

    there's nothing you could have done

but what you did
