Does it really matter too much whether Antjexix put her post on Health or Dieting? She was asking for advice and help, not criticism.
I too, can identify with binging on 'rubbish' food. After all, who binges on a bowl of salad? There are periods when I go into the kitchen and grab handfuls of crisps, or take 3 chocolate biscuits (kitkats, penguins etc), and hide the wrappers in the bin. I can't be given a box of chocolates without having to eat them all, practically at one sitting. I'm 5'8" and 12 and a half stones. I feel most comfy in a size 16, but that's because I don't like my clothing to cling, and a 14 would give me a muffin-top waistband.
I've dieted on and off since the children were tiny, and have accepted that's probably how I'll always be.
If I were worried, as the OP obviously is, then I would see my GP. There's no reason why she shouldn't have her concerns addressed, neither should she feel her worries should be treated lightly. Bingeing on food can also be looked on as self-harming, surely.
