Hi gemi,
Sorry to hear about your mum, hope she makes a speedy recovery.
We are all using the app my fitness pal, I've tried slimming world a few times and just can't get on with it, weight watchers was brilliant years ago, I actually lost over 4st on the old points plan, but since they've changed it to smart points it's gone downhill.
My fitness pal is free and we do our weekly weigh in here for free 
I must admit the last 2 days have been difficult, it's been hectic so I used that excuse to snack on crap, however I still count the calories each day, I've gone over my allowance but at least I'm aware.
I find sticking to the same or limited breakfast and lunch choices helps, cereal such as weetabix, porridge, special k for breakfast, lunch a sandwich or roll with various fillings, that way my evening meal is something to look forward to. I allow 200cals for evening snacks too, my worst time is once kids in bed, I want to snack or binge! By allowing a few hundred calories for this I can control it.
3 meals a day plus my 200 calorie evening "treats" seems to be working. I've had good days, bad days, bad weeks etc but still sticking with it and losing slowly.
