okay, to be honest, i think you could be eating MORE. It's really easy to be on a diet or lifestyle change and feel like you're doing good b/c you ate less. but it won't last if you keep depriving yourself. this is why i do so well on WW, b/c I know everything has a point value, and it's just a matter of balancing good choices and my ever-present cravings. haha. this way i don't ever 'cheat' even if i go to taco bell or eat a slice of cheesecake or whatever... i just have to hold myself accountable for it. i don't know what brands and types of foods you ate today, but i'm going to give a guestimate just to give you an idea of how you didn't do THAT bad even with your binge:
yogurt 2
granola, maybe 3?
2 sandwiches 7 (assuming no mayo)
curve bar 2
ziti 6 (i had that too

)
light string cheese 1
3 chips delux 6
so you had 27 points today.

that's totally not bad. you said you're what like 5'3" and 170? your daily points allowance is probably like 24ish, plus you get an 'extra' 35 points a week to divide up however you want... so you are SO totally fine, girl.
now, to look at it this way -- WHERE THE HELL ARE YOUR VEGGIES?!
if you had paired your ziti with a salad with carrots and cucumbers and tomatoes, onions, mushrooms... you would have felt much fuller, gotten in tons of veggies and fiber... and it would have been ZERO points, aka hardly any calories at all!
just think about all the 'freebies' you can add that will help... like a pickle (0 points or like 5 cal) with your sandwiches at lunch.
bottom line is, even if you felt like you binged, you binged on BETTER foods than mcdonalds or whatever. and if you feel like you just can't live without some burger king, fine, but get a small fry or onion ring, and a regular cheese burger... just see what LIFESTYLE CHANGE type choices you can make to make a bad choice better and still enjoyable. then spend the rest of your day eating low cal / low fat/ low point foods to balance that out. have a 2 point or 100 cal oatmeal for breakfast, the warmth makes it especially filling... you know what I mean, just BALANCE, MODERATION, and PORTION CONTROL.
but don't beat yourself up, you didn't blow today by ANY means.
keep it up!
