How do I get my family to understand my diabetic needs, such as foods,meds,ex,....

Well I've got this problem with my family you see I've been a diabetic for years now and kind of know all the do's and the don't of managing my diabetis, but around my loved ones it changes dramaticly like how I eat or what I'll eat around them......

It's kind of the base of my weekness, I don't want to sound like someone that blams everyone else for there miss-fortune but, i've found out that as far as a day to day thing they could care less about me, only if i'm sick then it's why arent you taking better care of yourself you know thats bad for you or have you taken your shots on time? did you take all of your med's this is my wifes big concern!

I no it's my life and my responsablity but the nagging sometimes drive me to a point of not caring about anything I do..... and yes I know good health starts with a good attitude and thats allway's a personal point of reference that we all must identify with ourselfs as  being diabetic but can anyone tell me why it's so hard for them to understand what we are going through and the impacked on how we do it........
