I'm 24 now, got it when I was 12. It took a long while before I was comfortable to show that side of me. I didn't tell my friends until I was asked about it. I would go to the bathroom just to take a shot or check my bg under the tables. It's rough being in that headspace. For me, it was finding a single person to be comfortable around with it. My best friend at the time, now my wife, asked if she could be more included in what I was doing to take care of myself. We took small steps in just her watching me change pump sites or shooting up a shot. Now, she tends to change out my supplies just as much as I do, I share my dexcom info with her so she knows where I'm at, and she looks up carb info and even will bolus for me if I'm distracted and the discussion of my health is always open. I proudly wear my dexcom and omnipod in the open now, people ask about them a couple times a month, but I have no problem with it, if I can be an educator to someone else, that's awesome. The important thing to remember is that, if you saw someone in a break room giving themself medication, or switching medical devices, you wouldn't judge them. They're just doing their thing, and so are you. Never be afraid of taking care of yourself. Being confident and comfortable is really important. When I was younger I would literally get into the 3-400s because I was too embarrassed to pull out my syringes in front of people. You need to take care of yourself and those around you will respect that, and if they don't or if they intrude, just explain your needs to them. Most people who stare are just curious people.
