My heart goes out to you and your son, especially since he’s probably struggling to express how he feels about all of this. So often it seems they try to keep it inside so as not to disappoint or upset parents, and they don’t have the vocabulary to identify everything that’s going on with them.
Statistically speaking, there are probably at least a couple of kids in your community with T1D, depending on where you are, but they may not be in his age range. Kids just a bit older often like to feel like they can mentor or help someone younger, especially when there’s a little common ground. Contacting your pediatrician and/or endocrinologist to find support group information might help, and if you’re in a smaller community, making an occasional day trip to a nearby bigger city to meet with other kids might be a big hit with him, especially if there are some unrelated activities he can look forward to.
