Hi Olly, welcome to the forum
🙂 Very sorry to hear about your diagnosis

It's one helluva shock isn't it? I was diagnosed a week before I was due to run a marathon, so it was one of the furthest things from my mind when I suddenly became very ill and then was diagnosed.
There is an awful lot to take in, so try not to get too overwhelmed by it all. How are you doing with the injections? Sounds like you are on what is known as a basal/bolus or MDI (Multiple Daily Injections) regime, with a slow-acting insulin once a day and fast-acting with your meals? Which insulins do you use? The good news is that this is one of the more flexible insulin regimes, allowing you to eat (or not eat) what you want, when you want (within reason, of course!). Some insulin regimes force you to eat certain amounts at the same times every day, which can be difficult to live with at times.
Don't worry, you will gradually get used to things and as you gain more experience with how your body reacts to things lif will become more predictable. Have you been taught to carb count, or are you on fixed doses currently?
I would highly recommend getting a copy of
Type 1 Diabetes in Children Adolescents by Ragnar Hanas It will explain everything you need to know about living with Type 1. Well, maybe not
everything, but for those things it doesn't, you have us!
🙂 The good news is that there has never been a better time to be diagnosed as knowledge and treatments are improving all the time - it would have been a very different experience even only a decade ago. Still a pain, but easier to live with.
If you have any questions at all, please let us know. There are lots of friendly, experienced people here who have all been where you are now, and any question you may have will probably have happened to someone else before.
I look forward to hearing more from you
🙂
