@doyoutakesugar , it's occured to me after reading this thread that in the almost 30 years I've been T1, during which time I've done countless shots/tests in restaurants, bars, cafes, trains, buses, street, in major cities in Europe and Asia, and backwood places, in full view and never shy about it, I can't actually recall
ever seeing anyone else taking a shot in public.
Statistically, demographically, law of chances, however you want to put it, another fellow insulin user
must surely have injected from time to time within my eyesight, in the same bar etc. etc.
Yet, in all that time, I've never actually seen anyone else injecting. If I, as a T1, doesn't notice someone doing something I'm familiar with, which must have happened in my general vicinity at some point in the last 30 years, it just goes to prove the points a lot of posts here say: no-one notices; it's discreet; people who do notice aren't fussed.
Your post title asks about who is troubled by injecting in public. One of the aspects which you're looking at is the worry about people seeing you: you've said as much in your opening post. Is an answer maybe that people are worrying about nothing, because, based on my experience of never having seen anyone else injecting in 30 years, no-one actually does see you, including most Ts, not because we hide away in toilets (I'd punch, or at least mildly disagree with, any waiters who suggested that as an option), more that the whole deal is just very subtle? Or when they do notice, they just say, hey, ho, guy's just sorting out his condition?
Short true story to get my point across:
Used to pop out to my then local at the weekend, few beers, meal, plenty of injections sitting at the bar over the years, same barmaid for three, mark it, three years, she finally noticed me in year three taking a shot, says to me, "Scott, didn't know you're diabetic, should've said." She said that because one of her relatives is T1 and she wanted me to know if I was ever dropping, wave a hand and she'd be out with the apple juice and biscuits pronto on the house (didn't have the heart to tell her I always
carry). But it makes the point: no-one notices if you don't want them too, even if you're sitting in front of them for 3 years. And when they do notice, or you choose to tell them, people will go out of their way to make sure you're OK, because, in general, that's what people are like.
Here's a post-grad thing for you to do. Go backpacking round Europe/Asia, take a few selfies of you injecting in the main squares of some major cities (main square, Rynek Glownie, Krakow, Poland, is definitely, in my view, the most beautiful of all of them), post them here. You're recently dx'd, you've got your worries about public injections, but after a while, doing that sort of thing will become, "...and I was worrying about that, why...?"
You'll figure out an answer to all of this. We all do. Best of luck, mate.
