Yes but above all those things about experimenting and being confident it also says "don't get high blood sugars or you will die a young blind amputee."
My parents sometimes remind me that in the first few weeks after dx, I was pretty strung out about the possibility of going blind and losing limbs. We had a few arguments - they would be trying to reassure me that everything would be fine, and I'd be, oh, like, how can you say that, people go blind from this. So, I can understand where you're coming from on this.
But time passes, and I reassessed things.
No-one can give you any guarantees about complications. It's been said that the best we can hope for with T1 in the long run is a no score draw.
But I reckon that we can score small goals along the way. Each time I go along for a review and get a decent a1c, that's a win. So is still feeling all the jabs with the foot prick test. And getting a no signs of diabetic eye changes letter after an eye test. Even the occasional ""early signs of eye changes" letter isn't all bad.
These tests are there for a reason - they are an early warning system to pick up on complications so they can be treated before they progress to anything serious.
I know you don't want contemplate being T1 for years and years.
But take it from an old timer: the fear of complications fades as time passes. It's something I still think about from time to time but I keep it in perspective, derived from the fact that even though I was a bit wayward in my twenties, I'm still running fine in my fifties.
I worry that your fear of complications is consuming you. Understandable as you are so recently dx'd. But try to take some reassurance from all the people who have been there and done that, that provided you make a decent effort to stay in range most of the time, you are massively improving your chances of avoiding complications.
Note I said "most of the time". The occasional short flyer up to 10, 12 or even 15 while you spend a bit of time experimenting with food, doses, timing will not do any long term damage.
Making some mistakes in the early days is inevitable, and it still happens in the later days because of the inherent unpredictability of T1, but the point is that going out of range from tine to time for short periods is not that big a deal in the long run, so don't be consumed by worries that you're doomed unless you're always between 4 and 7. That doesn't even happen in non-T1s.
