Welcome to the forums.
My gp sent me to hospital as my blood sugar level was so high and I had ketones whatever that means, I'm so new to this and quite confused. After 6 hours in the corridor and waiting room I was sent home with metformin.
Pretty sure that they shouldn't have done that, given that you had /have ketones as diabetic ketoacidosis is a real risk for new T1s and it kills without insulin.... (However, you're still alive
). I suspect they just looked at your weight and age and assumed T2, and got you out of there as soon as possible because of COVID.
Anyway, the good news is that you have a T1 diagnosis
before going into full fledged DKA. (Your bg levels are very high and you need insulin to bring it down and it would be better if you didn't have to wait another 36 hours before you get that insulin. Don't be afraid to ring 111 if you start to feel even worse before Friday, you really need insulin now.)
Anyway, the good news is that insulin will bring your levels down, and as a T1 you have more dietary freedom than T2s, as you're not carb intolerant, it's just that your body isn't producing enough insulin for those carbs. And modern technology for T1s is improving every year, so in the long run it should become much easier for you once you've got used to the whole thing.
So, get used to insulin being your new best friend, it's a balancing act but one that you will gradually learn to perform. Those blood sugar levels (probably with ketones) will be making you feel ill at the moment, but the insulin will bring it down and you should start to feel better soon. But they'll probably start you on a low dose of insulin and bring your levels down gradually, as too sudden changes in blood glucose can be damaging to your eyes. Also, too much insulin can cause hypoglycemia (low blood sugar, the bane of any T1's life) and they don't want to induce that.
There's a big learning curve for T1, but you don't have to do it all at once. Feel free to post here for advice and/or sympathy, as it's an international forum there's usually someone online.
Good luck.
