I can sympathise, it is a troubling time, but in reality, very little does change day-to-day.
Type 2 runs through my family, however, I do believe mine was purely self inflicted by a poor diet, and sedatary lifestyle. It sounds like he is doing the best thing, and trying to take it as a positive thing, which is what I did, and to be honest, its the best thing that happened to me, it is important to realise that without positive changes, diet and excersice, then it can have quite an impact on your health in later life.
Has he been getting other symptoms?, I remember getting really bad thirst and having to wee all the time, so if he's not been getting any symptoms then maybe it may not turn out to be type 2.
I can also understand the needle thing, its not nice, but I had to get used to it, I remember when I was first diagnosed I was getting bloods done left, right and centre, so its just one of those things that you have to put up with unfortunately, now its only 6 monthly, and a yearly flu jab, so its not too bad!.
I am sure if it does turn out to be type 2, then he will get good support from the health service, because they were very good with me, the only bad thing they did was put me on diet pills, which were AWFUL so I quickly came off them and just got on with losing weight myself.
If either you or him need any other info, or just a sounding board, I'd be happy to help out, even if its just to reassure that life goes on, and it doesn't have a negative impact at all really.
Good luck to you both
