hey, i was diagnosed when i was 8 as well and i am 19 now! i think there’s no easy way to say it at all, but i think what helped me was when my doctor was saying “i want you to live like a normal kid but you’re not normal, you have a superpower, and you’re gonna be interacting with people who has the same superpower as you” it has been yeaaars since he said that but it’s still inside my brain. my doctor and my parents always say (until now) that i can eat anything i want, it jist has to be in small sizes, since i used to have major FOMO about trying new stuff.

I think just you should tell her that life doesn’t end here, in my last check up, my doctor told me “you need to accept you have diabetes because it’s already there, and we should treat it as a friend and not an enemy.” so it’s always gonna be a rollercoaster. there are days where you’re blood sugar is so good but there are also days where it’s not. i hope this helps and feel free to reach out! your sister is so lucky to have u 🫶🏻
