What Do You Do?

What do you do when the one you love doesn't love you back,
when all you think about is the smile on her face,
when everyday you yern to be in her life,
when everything she does just gets you by,
when the love for her is so strong,
that every time you think it might be wrong its totally not,
what do you do when the only thing keeping you alive is your best friend,
and they don't know how much you love them,
but its more then a friend.
