When to stop losing weight

I’ve lost just over 6 stone since April last year, I have been taking mounjaro, was up to 10mg but have weaned myself back down to 5mg because I’m worried Asda will stop my prescription at some point now I’m a healthy BMI. I’m just about in the healthy weight bracket but ideally would like to lose another 2 stone to be right in the middle so I have some lbs to play with when I eventually stop the meds. My issue is that I was a size 18 and now a 10 but everyone around me is telling me to stop and I’m slim enough, etc. I am 40 so the loose skin issue is bugging me but I really feel that my stomach needs to lose another 2 stone - it’s where I carry weight. I am aware though that I do not see myself as I am, I genuinely still see the same body shape as 6 stone ago despite knowing it can’t be possible. How have other people managed dealing with everyone else’s opinions, and your own body issues? Sorry for the ramble!
