Hmm, I'd put money on you not getting enough water if you're in that position amax I will challenge you to this.... It's half term next week, see if upping your water by a litre (or two) every day doesn't make a difference. If it does, you could continue after half term by really going for it water wise between the hours of four and eight. That way you can piss freely 
between eight and bedtime....
If it doesn't , just keep tweaking, and coming on here posting your grub, and we will get you sorted
Now ehric hopefully stuntnun will come on and do science words in a bit to ease your panic, but in the meantime, here is my garbled version.
The idea is this, yes, you obviously need to eat less than you're burning to lose weight.... What should happen is this. At first you eat when you're hungry while your body adapts to fat burning. Then, what happens is you start producing less of a hormone (either grehlin or lepton I think) which is the 'hungry hormone' and so your appetite naturally lessens.
Basically, in most people, eating the proper ratio of fat:protein:carbs prevents overeating, and gives enough satiety to actually lose excess body fat.
I really struggled with the idea of upping my fat intake, but I gave it a go. In the weeks where I wasn't losing, it became apparent I was consuming too many carbs, or too much protein. It is extremely difficult to overeat on fat alone. It's the other two you have to watch, and if you get the water down you, that really really helps.
Protein is easier to overeat on than fat, and if so the body converts it to glucose.
So, with all of that in mind, why not try to put together a menu for a week that you know is the correct ratios, and perhaps slightly smaller in portion than you would expect to eat, and makes limited use of dairy.
Basically, buttery eggs (one or two) for breakfast, then perhaps something like a homemade clear chicken soup, with extra butter and a few good carb veg in it, or half a tin of tuna in Mayo, with cucumber, radish, celery in.
Dinner can be basically two chicken thighs, or two bits of pork belly, cooked in the oven in butter, and with a few bits of courgette, or some roast peppers or aubergine ( but they should only make up about a third of your plate imo)
If you're a caffeine user, see what happens if you ditch it for a week or two.
If you're hungry between the three meals, interpret that as thirst and get
more water in. I'd be staggered if that doesn't help get things going.
Apologies if you are already doing this, please feel free to tell me to bog off but know that I feel your pain, as I have totally been there myself.
