T1D can be embarrassing
It's awkward enough having to fiddle around with your blood testing kit, an insulin pen or pump dozens of time a day, let alone deal with those around you staring as you do. T1D remains a hidden condition until you need to test your glucose or bolus when you eat.
Although nearly always in curiosity, having people stare and ask questions as you go about your business is uncomfortable and irritating. "What does that do", "What does that number mean?", "Are you going to stab yourself now?". If you're anything like me, I prefer my diabetes to be managed in private and out of the spotlight.
Having T1D can make you feel 'abnormal' compared to your peers, especially in school. The last thing a teenager wants is to stick out like a sore thumb because of a medical condition.
Having T1D comes with fame and attention, only we didn't ask for it.
Face the fame.
As annoying as it can be to feel like you're being watched, take it as a compliment. From experience I've found that most observers are simply interested in the whole concept of diabetes. Most don't know what T1D really is and see your glucose metre or insulin pen as technology from another planet. Comments such as "I don't know how you do that" or "How many times do you have to do that a day?" actually made me feel quite resilient whilst I was in school, and even today.
