staggering, stumbling, still staying strong

You know you'r gonna lose someone
and there's nothing you can do about it,
nothing you can do to make it go away
but you try your best anyway.
It hurts so much to look at her
but you cant afford to stay apart;
Making new memories everyday,
not knowing when her screaming heart
may suddenly cause a deafening silence,
not knowing whether to let her know
how much it's killing you too
or to be the one to show
that she's really stronger than she thinks
and assure her that it will pass
when you do not know for sure
if she even stands a chance.
You cannot tell her you understand
because you know you don't.
I guess the best you can do
is be her friend
until the very end.
