You sound much better than you did in your initial post! Hop on-line and check with the American Diabetes Association about kid support groups in your area. This could open a whole new world for him. If there's one nearby, there will most likely be youth groups, forums, trips, etc. for him and others.
Make sure that if there's one around a nutritionist who deals primarily with children. This will take a lot of the mystery of how the carbs/protiens etc. affect his body.
Don't let him mourn the past make sure he's anticipating the future.
By the way, there are also special summer camps for kids with JV.
Remember what I told you about buying meters, test strips, needles, even alcohol swabs. Get prescriptions for every little thing - they'll be covered under most insurances.
Get the school nurse on board as well. She'll be able to remind him about testing and shots. Make sure that you educate his teachers, paras and other staff members (Occupational Therapist (OT), pt, speech - anyone that he interacts with) as to the symptoms of high or low blood sugar.
PM if you need anything. It's not a nightmare, just a different way of living!
