What works for me when trying to abstain is to actually allow myself a small amount of what I should not have once a week. I usually pick Friday as the day I can have 1 'naughty' thing - I call it the 'Friday rule'. That way I'm only not having a chocolate biscuit / icecream / whatever until Friday. It is important to only have a small amount of what you crave and to never, never allow yourself to move the day one forward. 'I'll have a bun on Thurdays and nothing on Friday' doees not work! And, for me, an entire day off from dieting would undo the entire week's effort - though I understand that's not the case for everyone.
The 'emotional eating' question is a big one too. I know I eat when I'm bored / lonely / upset - And of course there's always the 'oh my God, I've broken my diet, what the effin point I'll eat a tub of icecream' moment.
It is hard, Sparkle, especially if you are trying to do it alone. Can you find a diet-buddy? Going to the nutritionist weekly isn't really going to help - have you tried a weight loss group, like Weight Watchers? What kind of 'self-motivation' have you tried? Because, really, no one can motivate you but you. It has to come from inside. I don't know what hardcore advice I can offer other than you need to work out why you are unable to stop yourself eating these foods. You can't really treat the symptom without knowing the cause.
I live alone (well, no other adults, I mean) and I know I over eat because there is no one to be disgusted at me finishing the pack of biscuits - I had the same cravings when I shared a space with another adult but it was much harder to indulge them without being noticed. I'm having to address that now and try to be my own 'audience'.
I hope some of that is at least a little bit helpful - I wish you luck and courage, mainly courage
