Hi,
I know how hard this is. Our little girl (8) was diagnosed in December '12 as well. I was so worried about her (she was very ill when diagnosed). Now though, things are feeling less stressful and I am slowly becoming a bit more confident. It helps enormously that she doesn't mind all the injections. I've also found it really empowering to try and educate myself as much as I can, so I can make the best decisions for my child. How is your son coping with it all? Our kids are amazing aren't they? So much to deal with, yet they seem to be able to accept things easier than us grown-ups at times!
Please know you are not alone. It's so hard not to worry, I know. Try and find strength in knowing you are being the very best mum you can be for your son, that you will help him to gain great control over his diabetes. I prefer to see diabetes as a challenge, rather than an illness as such. It's early days still, allow yourself to feel angry and sad - all completely natural. I still get teary sometimes, thinking of the unfairness of it all. But not so often anymore. Parents on here all seem to say the same, it WILL get easier.
Take care
