People around me, family, friends, work mates, have always been very understanding.
I suppose it depends on how much you tell them.
As you know yourself, it ain't that easy to manage.
A lot of non-T1s think, aye, ok, no bother, just a bit of insulin for each meal, nae problem.
I don't shout about my T1 at all, but I've been playing around with cgm for the last few months and, just out of the sheer novelty of having bg levels pushed to my phone/watch, I've been telling people about it and why it's important for me to use it so I can keep in range as much as possible.
The surprising thing is that they're actually interested in it - some of them have T2 relatives, others say, Scott, I really didn't realise it was that difficult, respect.
Don't be shy about this at all. It is invisible to an extent, but I'm never slow to say, aye, that's a nice looking bit of cake, but I'm going to pass on that.
