Hi
@Gardevoir and welcome to the forums.
Just over 100 years ago T1 was a death sentence, 50 years ago it was a life shortener but today with the aid of modern technology the prospects for new T1s are bright. It's one of the few illnesses where the patient can manage the illness rather than having to depend on advice from the medical team. (Though at this stage you'll be very dependent on your team).
I've been T1 for 53 years so have seen and benefitted from the improvements.
Your hba1c corresponds to an average blood sugar of 17mmol/L over the last 3 months, so I expect you've been feeling quite ill. I expect your team will advise you on how to increase your dose gradually to normalise your levels, they generally prefer to do this slowly, partly because you don't want to overdose on insulin and partly because it can be better for your body (specially eyes) to make the change slowly. Please resist the urge to buy any expensive new glasses while you are adjusting back to normal, as high blood sugars can effect your vision.
At this stage you have a massive amount to learn but my advice would be to remember that this is a long term process (marathon not a sprint) and you don't have to learn it all at once. My single most important piece of advice for a new insulin user is to always carry some form of sugar with you. If you get hypoglycemia (low blood sugar) you can become confused and you want to make it easy for yourself to find the sugar you need.
Once more welcome.
