You never knew

My life has been sad leading up to this place,
'Cause you saw everyone, save for me.
and now every time that I look at your face,
A sadness wells up inside me.

I cry myself to sleep at the thought of your name,
And I wonder why life brought this sadness.
and now every day I feel just the same,
I feel it will drive me to madness.

But I can't let you go! No, that'd be too hard!
And forgive me if this may sound sappy:
Although you broke my heart and took every last shard,
you're the only thing that makes me happy.
