Hi Mel,
I can definitely relate to how your son is feeling. I was diagnosed when I was five but I'm just a few years older than your boy at the age of nineteen. I only really got decent control on jabs after I did my SADIE course (equivalent of DAFNE) and my control is now even better having got hold of my pump which I got a few months ago.
As for gaining control, well, it's up to him more than anything but if he is to go to university he'll have to be able to control himself before he goes to uni. I started taking control at the age of about sixteen or seventeen. I'd highly recommend that he goes on a DAFNE or your local equivalent. Having said that, what's best is that he meets other diabetics. It helps so much, I only met other diabetics when I joined this place and did my SADIE course. It really helps. I'm more than happy to chat to him by Facebook, MSN or things like that.
Tom
