Hi Citrus2512,
I'm really sorry your son and you are going through difficult times! Lots of good advice from other contributers there.
I was diagnosed T1 at age 12 (36 now) and for the longest time, I did not take care of it properly (I wouldn't do my basal injections, skip the humalog regularly as well, would not check my blood glucose). And I would NOT accept any comments at all from my parents. I felt isolated, inadequate (because my body couldn't function normally), so different from my friends. And I felt this huge sense of responsibility which I thought was unfair, scary, and overwhelming. The talks from the doctors about how I would lose my eyesight, my limbs, not be able to have kids etc just reinforced my shame about my body and about my inability to be a responsible diabetic.
In retrospect, what would have helped at the time:
- Having someone with diabetes to talk to about the struggles, or being able to read and comment on this forum for example

- Having someone not tell me what to do but asking what I struggled with and what kind of help I could have
- Understanding (and my parents as well) that blood sugar results are somehow always going to be up and down, and that every little progress counts
-Knowing from my parents that being a good diabetic is not the only thing they want to see out of me, and that they are proud of me even if my blood sugars aren't good (I now they did but would have been helpful at the time to hear it from them)
- Having a regular activity with my friends and / or family to take my mind of diabetes
I only realized the importance of diabetes once I was in my 20s - as others have said, your son will need to realize that on his own. Everyone is different but I hope some of the suggestions will help your son (or at least let you know you are not alone!)
