It's okay! :)
As others have said, you are human. And beating yourself up and feeling like you let yourself down is not a healthy cycle to get into. In my experience, as an emotional eater, I know that if I beat myself up for making poor food choices, I end up making MORE poor choices, trying to comfort myself. That is no bueno.
Instead of the guilt, put a positive spin on it. I would say to you, "You slipped today. But you are still on a healthy journey. You are aware of your health and what you are putting into your body, and awareness is the first step. Learn from this, and accept yourself. Fear and guilt and shame are false friends. Get back on track tomorrow and forgive yourself for today.:"
