Weighed in this morning, and in the last 2 weeks, I have gone from 13st 9lbs 2oz to 13st 9lbs 0oz

Weirdly though, even though my weight hasn't gone down much, I've shaved half an inch off my waist measurement and gone down to 36" from 37" ( measuring just above my belly button and breathing out, as they tell me to online

)
I didn't weigh in last Friday because I knew the previous week wasn't going to have been pretty. It wasn't over the top, but I knew I'd eaten too much to lose or maintain whatever weight I'd reached. Out of the previous 14 days, I think I'd have been significantly over my calorie goal (or even maintenance) 7 times.
I was disappointed when I first weighed in, but then I looked back at the last 14 days of food, and saw that I've had roughly 1 good week, and 1 bad week, but they were very much mixed together. I initially felt more hard done by because I've worked particularly hard to get myself back on track this week, and of course you want to see immediate results subconsciously, even though you know it's not practical. I don't weigh in more than once a week on a Friday, because I don't want to hyperfocus on what I'm weighing on a particular moment, and am trying to average food over the 7 days so that I don't feel so bad about eating a nice pizza, or going out for a curry with my mates.
We don't have any big family party buffet meals or restaurant curries with mates planned this weekend, or this week. Next Friday, we head down for a weekend away with my in-laws in Devon, and it's likely to fall apart by then, so I do really need to focus on a good week this week. I think a good weigh-in next week will put me in the right frame of mind to try to protect my goals while I'm down there. I hope!
I FEEL a lot better at this size, and I'm noticing the same benefits as
@Raymond Lin in that my Watch is tapping me to tell me that my resting breathing rate and heart rate have been lower since I started losing weight at the beginning of March, but I need to work out some sort of framework for how I make this sustainable long-term, because right now I'm still very much focused at getting down to around 13st 6lbs, and not so much at how I regulate my intake to remain at that weight, despite still loving my food, and working out a technique that lets me cope with / suppress hunger, even at maintenance calories.
