That sounds like a fabulous update, and great progress. Until I read about the funding aspect, I as thinking the weight measure was probably just some form of benchmarking exercise.
Curiously enough I was considering all this weight loss stuff just this morning, as I had read elsewhere of folks feeling almost exactly are you did. I suffered from an eating disorder many moons (read 3 decades) ago, and it still held some fears (of regression) for me, until relatively recently.
When diagnosed I concentrated on my blood scores as shunned the scales completely. I didn't carry much weight, but I had some luuuurve handles and a bit of a muffin top waistline in close fitting clothes (a lovely image, eh?). Once I had lost weight, then started wanting to stop that loss (for fear of becoming unhealthily thin again), I needed to weigh myself or I would have no self-help tools. Only this morning did I really realise/admit that I am in a better place, in terms of my relationship with the weighing scales than I have been for probably 40 years. Now I just see it as one of those things I do. Hopefully, you can, over time, get to a similar place.
On a really positive note; when I was being discharged from care (all that time ago), I raised worries of regression and using the revolving door into and out of health. I was told then once I had a decent footing in a good place, I was much more likely to get hooked on something different, rather than weight or eating - or not eating in my case. Obviously, I'm trying hard not to let that happen, but if it has to, hopefully I'll enjoy whatever I get overly keen on.
Go for it. I bet you'll soon feel miles better just having taken the steps you have and knowing you're going to have some decent support. I know I did.
Very, very well done on doing the scary thing. Give yourself a big pat on the back.
