WWB - that's brilliant that you didn't turn to food after a stressful morning and I just cannot believe the attitude of the teacher - when her tooth had gone through her lip, for heaven's sake!
I've gained 1lb. Assume its ok just to let you know here, don't have to email you as well, do I?
Bingeing in secret is awful isn't it? You know its wrong, you know its not going to make you feel any better, and yet something takes over and makes you behave irrationally. Is there any way you can give yourself a break by trying to spend less time alone? Easier said than done, I know, sometimes, and you're hardly likely to want to do housework etc in the company of other people, but just a thought.
If you like to eat frequently, could you plan lots of snacks into your day? Perhaps make every other one a healthy one and the ones in between a treat, but in a reasonable portion?
I don't know something like this:
8.00am Breakfast
10.00am Healthy snack (piece of fruit, or glass of juice and some nuts/seeds, or a yogurt)
12 noon Early lunch with some sort of treat attached (bag of crisps, 2 finger kit kat)
3.00pm Mid-afternoon snack (vegetable sticks & hummus, or yogurt, or one piece of toast & marmite)
6.00pm Early dinner with family (if that's how you do it) no puddidng, but then allow yourself a
9.00pm mid-evening treat like a few chocs, or a cup of tea and biscuit
or
Small snack when children eating their tea (perhaps a controlled amount of their left overs, or another little treat like a piece of cheese and some crackers, or a cup of tea and one or two biscuits)
Later dinner with DH, followed by a healthy snack like fruit again.
You've mentioned before that you eat reasonable portions at mealtimes, so if you give yourself permission to eat frequently at other times during the day, then you might not want to try and cram in loads all in one session?
Just a suggestion offered in friendship and with deep respect!
