Hi Justine, welcome to the forum. It can be really difficult to say out loud that you are struggling with diabetes. I found myself trying to be really together and learning everything, and trying to understand what seemed so simple to everyone else when I was grieving for my son's freedom and childhood! My younger son was dxd Oct '09 aged 9. There is so much to learn and so many changes to implement at home, at school, sports, friends houses etc.
It is okay to feel overwhelmed, and to feel sad and angry, too sometimes. It is also important to ask questions again and again until you understand, or feel comfortable with the answers.
And sometimes it just helps to talk to others who have gone through a similar thing to you. This forum has helped me so much in the past couple of months with questions about D, silly jokes, and discussions which have nothing to do with D!!
Hang in there, I believe it gets easier in time.
How does your son feel about his diagnosis? Once my boys had met other children with D, they chilled out a lot!
