I know exactly where you are coming from, I have a teenage son diagnosed in June 2012 he is now nearly 16 years old. My son has other problems as well ADHD and OCD, he is I finding this hard as he can't carb count, and won't try at present, so I am left totally in charge of working all his shots out. It's made him very angry as I am always having to ask what he is eating and how much for lthe 3 meals a day. Also he is very isolated as he can only go out after breakfast but back before lunch or go out after lunch but back before dinner.
All his friends have dropped him as they want to roam about all day and go to chippy or corner shop, and he does not know how to work things out, also I feel he worries he will get it wrong and feels secure with me.
I have been told not to push it as he does do his own injections, and I don't want him totally rebelling. I constantly feel on his back and that he has had his life took off him because of this, it causes major upset and worry and I hate seeing him distressed about no one bothers with him now. I have boys stay at my house, and are even taking a friend on holiday, but not the same for him just chilling out, playing football care free.
It's so hard if you want to talk, it would be nice.
