How are you feeling? I'm feeling bereft.
"If an enemy were insulting me, I could endure it;
if a foe were raising himself against me, I could hide from him.
But it is you, someone like myself,
My companion, my close friend,
With whom I once enjoyed sweet fellowship
As we walked with the throng at the house of God."
Psalms 55: 12, 13
