You've had weeks and weeks and weeks of 100%, and you know as long as you're 100% you can stick to it.
And then you go to an Olympic torch event today and your sister (who you usually don't get on with at all) goes off and buys you a waffle, with ice cream and chocolate sauce not knowing you're on a diet. It's such an unusual token of generosity.
And when she brings it to you, you say no thanks but she looks sad, and you've been so good watching everyone else eat all day, and made plans of what you can and can't eat and stuck by it so carefully, and suddenly end up throwing it all away by eating half the waffle monstrosity.
And then you come home and look it up and find its a good 40-odds syns worth of screw up.
And now you're finding it hard to get back on track, feeling like throwing it all away and just going back to the old you, even though its stupid.
And knowing if you'd just said "I'm on a diet" it would never have happened but you're just too proud to tell your eternal size 10 sister that you are, as you know she'll just say told you so after years of telling you that you should diet and telling you that you cant possibly be happy fat.

Tomorrow I will wake up fresh and try again, but my confidence is smashed and I'm on a massive sugar low.
