I can't say that 'I love you'

I can't say
That I love you
It causes too much pain

I can't show
That I love you
My tears fall like rain.

I can't whisper
That I love you
It's full of disdain.

I can't shout
That I love you
It's a poisonous bane.

I cannot communicate
That I love you
I wont say it in vain.
