Hi Hcnwills, I was diagnosed around 10 weeks ago. It's all a haze at the start, what to do, what to eat, how will I manage! But you do, don't let it get you down, be assertive and take control. The first thing to do is get a meter and test your blood glucose. You must record this along with everything you eat. Yes it's a burden and it takes time, but it's so important to understand what foods spike your bg. I use apps on my phone or tablet to do this. They are also on my wife's phone and tablet so she can keep an eye on me as I work away a lot. These are my fitness pal for the food, and diabetes connect for the bg. Like your self I'm overweight with similar bmi, since diagnosis I've managed to loose 16kgs,my Hba1c has dropped from 103 to 54 so it's not a hindrance to beat you.. I have difficulty because I work away most of the time, hotels at night and factories during the day. This is why I have taken bg testing to heart, against my doctors wishes (apparently it's only type 2 so don't worry). My bg was 39.1 at diagnosis and I still get the shakes on metformin sr1000mg at 4.5mmol. Ive now got lots more energy and can now exercise and swim. The other thing as many have said is dramatically reduce your carb intake this will help reduce your bg and reduce your hunger.
Keep smiling, keep asking questions and listen to your body, you will soon start to understand how you feel.
