dolly - how tall are you and how much do you weigh?
We certainly don't count calories when we're low carbing - or at least not until we get closer to our target weight. And you need to make sure that you are eating plenty of fat. I know it seems counter intuitive, given everything we've been told over the last 30 years!
Anyway, just to have a look at what you've been eating:
B: 2 or 3 scrambled eggs with spinach or half a punnet of raspberries (85g?) with about 125g greek yoghurt
the raspberries and the yoghurt will be pretty carby - stick to the eggs, or eat the yoghurt without the raspberries
L: is a big salad - salad leaves, half a red or yellow pepper, hunk of cucumber, then either some chicken and guacamole and feta cheese, or some tuna Mayo and a bit of cheddar cheese, or a couple of boiled eggs with Mayo and a hunk of cheese...
This looks fine - but are you putting a dressing on it? And not using balsamic vinegar!
D: last night was Thai prawn curry (coconut milk, prawns, broccoli, peppers) and cauliflower rice; night before was 2 LC sausages, broccoli, cauliflower and cabbage with a bit of gravy; Thursday was leftover chicken madras which did have chickpeas in it but I had it on it's own.
Again, fine - but avoid the chickpeas
Snacks: two large handful of walnuts/pecans/macadamias/almonds and 2 squares of 85% choc.
Not great - this also adds a lot of carbs very quickly - you should try and get out of the habit of snacking really
Drinks: not enough water, too much tea with milk, large glass of dry White or red.
Well you know what I'm going to say here ... 
Seriously, if you want to get the weight shifting, you really do need to get the carb levels down - and I suspect that if you added yours up, you will be eating quite a lot of carbs.
