Welcome @Rayna37!
@GuyMartinsSideburns - this jumped out at me:
I just haven’t done much by way of exercise due to feeling so bloody tired all the time
You said something similar yesterday, and so I say again - you're not eating enough!
B- coffee and milk, water
L- fancying cauli rice and something? Chorizo and onions?
D - no idea yet, dd wants to make soup after school, I think I'd like omelette and salad
This is all pretty low carb, but also low fat and low protein - and so low calorie and low energy! I know you've talked about finding it difficult to eat, but seriously you're not giving your body enough nutrition.
In terms of weight loss, it's not always good to keep everything low - the homeostasis mechanism means your body will be trying desperately to keep everything the same - you're not feeding it enough for it to switch to fat burning.
This, on top of the stress and cortisol is really a recipe for no weight loss.
I'm glad you've chucked out some clothes, as it means you won't have those 'hanging over you' - focus on the you that you are now, and buy lovely clothes for that!
I'm not trying to harangue you although I know it must seem like it but just want to help
