What Makes Me Want To Binge

Okay, basically the title says all. Yesterday, as I was chatting with my best friend, I realized what really ticks my whole 'eating everything urge' on. Zara (Friend, not 14 year-old cousin) was explaining to me that she had eaten too much during the weekend, and that she felt totally fat and useless. I asked her why she had eaten so much, and she said that it all happened once she saw her ex boyfriend again, looking hotter than ever.
"I got so depressed, next thing I knew, I was eating like a fucking pig." She weighs 52 kgs, and hasn't been able to shed any weight since we made the pact.
Anyways, that's what got me asking myself, What makes me want to binge? Depression? No. During those cases, I lose my apetite and just drink coffee. Aha! That's when I realized it: Whenever I am nervous, I eat everything in sight. That must make sense since I bite my nails in those cases as well. Maybe I'm just automatically wired to want something in my mouth when I'm nervous.
I haven't been good these last few days because of that. I had an oral presentation on Monday, so I was obviously nervous... and obviously wanting to binge. Which I did. It wasn't much, but it's enough to make me not want to look in the mirror. Plus, my scale is out of batteries.
But of course, when you have someone wanting the same thing as you, it's easier to get back on the bandwagon and ride to your destination (reaching your goal weight), since you both send thinspiration and beautiful positive comments of how reaching your destination will be.
I leave you beauties with a link to a model's video regarding diet.
*The only point I actually pay attention to is the first one since it defeats the purpose of binging and overeating:

"If it's really that bad, why would I want to be putting it into my body?
