Cider if you fancy joining us, @leesmum has kindly taken on the role of FitBit Mother and she generally sets it all up, I think she just needs your email address 
The hand burn sounds hideous, I've done exactly the same thing before and felt like a total doofus afterwards - medicinal wine definitely warranted!
Koko you poor love. I did see your other thread - I know you've had Diet Fatigue before, I think it just goes to show how bloody hard it is to lose weight in such a manic diet-driven-but-also-obesogenic environment. You can't move without having your head spun by it. I agree with Kick's excellent post - you feel confused and lost, but actually, you're the world's leading expert on Koko and Dieting! You know what doesn't work for you, so kick that to the kerb and permanently discount it and never think about it again. For instance, all those shakes and things that I bet you still have 
are not something you can stick to, so just cross them off the list. An actual handwritten list of everything you've tried might work, and then a thick black line through every one which you can't see yourself doing again, then you can stop thinking "maybe I'll try that one next Tuesday morning".
I also agree with Happy about making one change. I'd take it one day at a time. One day without snacks; one day with a clear meal plan which you stick to; then make it two, three, four, etc. I know others disagree, but as you know, I need an endpoint: "no snacks until Friday" rather than NOTHINGNICEEVERAGAINUNTILI'MSEVENSTONE. I feel like you sometimes have a good run, but you seem to give yourself such a hard time when you slip up, and go into a demoralised doom spiral, so it might be good for you to have slip-ups built in - that way, once it becomes a bit more of a habit rather than an endless wrestle with your own will power, you can slip up knowing that what we always tell each other is true - tomorrow is another day, you can put it behind you. Even if you just start by eating well and not snacking / whatever else on one day a week: say Monday. Just focus on Mondays, and then whatever happens for the rest of the week, keep saying "but on Mondays I eat protein and veg, drink water and don't snack" (that's my mantra, insert your own!); once you do one, it'll be easier to say "I did it last Monday, I can do it yesterday, and all that stuff I want I can have at the crack of dawn if I want it, just not on a Monday. Write it on the calendar, write it on Post-Its, write it all over your hand, really hammer it into yourself, just not today. It worked for me, anyway - I had to train myself into delayed gratification, because saying "you can't have that you fat pig, carrot sticks for you" just made me rebel at random (usually after three good days at the absolute most), whereas "you can't have that until Friday" kept my inner beast placated. It's a bit like toddler training - "if you get in the bath now you can have hot chocolate afterwards". My inner beast was a total toddler!
I know that advice ^ is what I always wheel out, so tune it out if I've said it forty times before 
Misericord lots and lots of us on this thread have had really awful times where we've completely forgotten about dieting. Don't feel like you can't post about it here, and we're definitely all in favour of eating to survive a rough patch. We'll be here to hold your hand, and also to drag you along if you have trouble finding the wagon again at the end of it
