Hi Firewalker. Welcome. 🙂
Firstly, I don't want to suggest anything is wrong bu just a couple of observations. I was diagnosed at 13 and am now 46 (with a grown up daughter), so I can empathise to some degree.
Your son's reaction to diabetes may be influenced by your own. If you find it hard to come to terms with, so does your son. You've done the best thing you can by joining the forum. Hopefully, you will see how many people manage their diabetes in so many different ways to suit their own situation.
Ive no idea how the counselling works, but are you getting any help from it too ?
I know many parents struggle with guilt, over-protection, etc and it may that he needs to feel more in control of it himself and feel confident doing that.
I'm sure he'll find his confidence with it very soon and will adapt it to his own lifestyle needs (and in turn, you'll be able to relax about it!).🙂
