What kind of response is that? You should be alleviated from your fears, not hit harder..... I have been diabetic since I was 10, and am now 49. I am happily married with 2 healthy boys and am very happy. What your child will encounter is an adjustment, and then the ability to self-control. You become responsible very quickly, but that is not a bad thing, if done with the right attitude. The hardest periods for me was a child, wanting to fit in and be like everyone else, but it seems that now things are so open, it's discussed openly - for me, it was a secret and nobody knew, including teachers.... I think having positive support from you, not being made to feel that 'you're not allowed' to have something helps.. Help your son come to terms with the fact that he shouldn't have certain things because they will make him feel badly. It's an adjustment in diet & lifestyle, but he will soon be a healthy eater. I think that as your body changes, you have to constantly adjust to your body's insulin needs, so regular visits to an outstanding endocrinologist is the way to go (don't just settle for a mediocre doctor). It helps to know someone, anyone else who has type I (I never met anyone else who had it as a child).
Did your divorce cause it? NO. Did the emotional upheaval set it off? Maybe. I remember that my onset came in the fall, and after a scare I had...are you aware that studies link diabetes to a virus that manifests in the fall - and that it is likely that you carried the potential for type I long before it manifests? Dont' be burdened by guilt. It is not your fault, your ex-wife's fault or your divorce's fault.
The best thing you can be is supportive - no guilt. no fear. That's what your son needs from you.
