Don't hate yourself, it's tough this dieting lark.
To ease your mind: I gained 12lbs during my week off over the jubilee. I haven't weighed recently but I expect there's loads on - I've been off plan nearly month thanks to being laid up for just over a fortnight. Anyway, gained those 12lbs - 1 week clean and green (roughly 1600 - 1800 cals a day and under 30g carbs) and all that had come off. Once you get back on solidly, no slips, you will be just fine.
If you can manage it - and only if you really think you can, don't do anything to make yourself struggle more - I recommend a day or two of just meat and eggs, mayo, a little cheese if you need it. It gets me into ketosis quick and stops my cravings.
Drinking absolute loads (say setting a 3l target) really helps me too. I know I'm losing weight when I have to wee 5 times a night!
Also please remember that you're still on the same path and you'll still get to the same destination. You haven't spoilt your chances. You've had a little sit down during a long walk and it may take you a few more minutes to reach your destination, but that's all.
I'm back on the wagon on Tuesday. We'll get there together.
Blimey! I'm surprised you have time to eat anything, good or bad!
