Emotional eating diversions...

Options
So, I had a pretty rough day emotionally. I fought every single urge to indulge. I made it through the day but it was sooo hard. I was so afraid of overdoing it at first that I didn't eat breakfast or a morning snack. By the time lunch hit I just had no desire to eat. Forced myself to eat an afternoon snack and then a reasonable dinner.

When you're in a state and want to eat everyting in site...what do you do? I know that I can't eat but I'm afraid that once I get started I won't be able to stop.

Any advice???
