Hi Beckah, welcome to the forum
🙂 Although it is a shock and will take some adjustments, it sounds to me like you are well-placed to keep your diabetes under control. As a PE teacher, I am guessing that you are quite fit and active and follow a good diet. I was diagnosed a week before I was due to run a marathon in May last year, so this is how I was when I embarked on my 'diabetes journey of discovery'!
Something you will need to pay particular attention to is how activity affects your levels. I would recommend that you get a copy of
Diabetic Athlete's Handbook by Sheri Colberg. I bought this book a couple of weeks after diagnosis as I was determined to get back into my running. You will need to find out the best foods for you to eat to keep your levels stable during periods of exercise, and how you may need to adjust your insulin doses as your body wll become more insulin-sensitive with the exercise. The book will explain all aspects of this and I found it to be very helpful from the start.
You will need to test your levels a lot to start with - before, after, and maybe during exercise, plus before and sometimes after meals, so at the beginning there will seem to be an awful lot of testing going on! But once you have built up an idea of how you are affected it becomes much easier. I test, on average, about 5-8 times a day depending on what I am doing and how I am feeling.
There is a learning curve, and it can be tricky at times to get things just right, but I managed to run the Great South Run last yar just 4 months after diagnosis, and have run it again this year. If you have any questions, please do ask and we will do our best to help!
