Yes.
People take insulin all the time around me. They just have the privilege of not being diabetic, and having their pancreases take care of it for them. LMFAO.
I have been a type 1 for about 19 years. When I was old enough to do my own injections (I finally got over myself and was able to do it at about age 12), I just did it in class, no problem. I have had teachers tell me I was “brave” for doing injections in class, like it is something embarrassing that I should want to hide. I never understood that.
I am now a teacher, and on the first day of classes, I tell my students “I am going to have to test my blood sugar and take injections during class. If you don’t like needles, I don’t like them either and I don’t have a choice. So just don’t watch.”
I frankly could not give a rat’s arse if people around me don’t like needles. I’m not doing it for fun or to shock people. If I am sitting close to someone, like at a cafeteria or on an airplane/train/etc., I will warn them that I need to do a shot, in case they want to avert their eyes. But I am not going to take my injection in an unhygienic place because someone can’t deal with seeing a subcutaneous needle. I have to do this ~ 10 times a day.
I am very thankful for the Americans with Disabilities Act (ADA), which protects people with Type 1 Diabetes, even though it is not often thought of as a disability.
