Hey Lucy,
I'm sorry that you feel uncomfortable about your diabetes at school. I'm 15 in 10th grade and I've had T1D for over 10 years. Having diabetes in school can be rough, especially when it feels like no one understands you. For me, since people in my grade have known me so long, it's just a normal thing for me to be a diabetic, so people know that this huge, loud rectangle on my waist is normal. But, before I got really comfortable, I had a rough time blending in too. It's important to know that people don't mean to hurt your feelings. Kids are interested in things that are uncommon to them. For example, some of my experiences were: stares when I needed to go to the nurse in the middle of a lecture, questions about what "that heart monitor thing is", and interrogations of my ability to consume sugar. The best way to help these issues is to answer these people's questions. Sure, it may be hard to hold in that scream and tell them, yes, you can have sugar. When people see that you're open about it, they won't become as interested. Imagine you're in class, and someone just suddenly drops their books and walks out. Everyone would start to stare at them and wonder what they're doing. But, imagine that they came back, and calmly said, "Sorry, I didn't mean to concern you! I have diabetes and I had to visit the nurse to check if I was OK." The next time they do that, people wouldn't really care as much, because its not anything new/different anymore.
