I agree entirely with viki, it may very well be a bit of a rollercoaster at first and a lot to learn but I think most, if not all, of us on here are testament to the fact that once you get your head around it you can make diabetes fit into your life, not the other way around.
So much of diabetes care is very individual and worked out through trial and error so take things one day at a time and don't let any mistakes along the way get you down. It may be useful to do a little background reading, there are a lot of useful suggestions in the recommended reads section. And absolutely take full advantage of your medical team, consultant, specialist nurses, dieticians etc.
