Please don't break my heart

My heart is just too weak
there's nothing left to break
I don't know how much of me
is left for you to take

I am going to trust you
like no one I've trusted before
as long as I don't find you
walking out the door

please don't break my heart
or tears will start to fall
I may fall apart
there'll be nothing left at all

I will do my best
to make this work each day
but you must do the rest
and that's all I have to say...
