It is ridiculous and you just have to figure out the best way to either inform people or ignore them. Because there are so many type 2's out there now, everyone has learned about diabetes through a type 2's "issues".
My sis in law was diagnosed with type 2 just a year ago and wanted to high five me as she said she joined the club when she saw me. I asked are you type 1 or type 2, and when she said type 2 I just go oh, mines type 1, I have to have insulin even for broccoli, I don't make insulin, mine is autoimmune.
A chiro I used to use just about 3 years ago told me she heard a herb was really good and reversed one of her patients diabetes. I told her no herb can reverse type 1, it can certainly help type 2's but it can't reverse my type 1. She then said but you didn't get it as a kid so you can change it. I told her no, I have the same thing as the kid disease, I just got it when I was older. It ended with her saying well, you should still try it.
So it can be very aggravating, it really is a constant thing. My main reply is I am a type 1, it's different, I have to take insulin for everything, even if I eat broccoli. Because frankly most people recognize broccoli as a healthy food and it makes them realize, oh it might be different then.
