I didn't want to read and run, I was exactly where you were a couple of years ago, DS1 was 7 when he was diagnosed and is now 9. He was petrified of needles upon diagnoses and sounds very similar to
How your daughter is now, he was diagnosed in the October and by the March/April he was injecting himself so you will find this will get easier. 2 weeks is still very early on and I think tbh the worst point as it kind of hits home how much it will effect day to day life, the information overload etc.Play dates are still doable, I accept at the beginning it was easier to host them myself, but found parents at the school have been super supportive, once he could inject himself it was much easier as I could give a meal or parents could carb count (I found an oven pizza to be an easy solution), I would test him at school (as I was there anyway with siblings) and determine wether to have a snack before he left, he would then test and insulin before dinner a couple of hours later and then I would test him again when I picked him up. Parties I tagged along at the start again but now he's okay to go alone, it's amazing if you involve them how quickly they pick up everything - he can measure and weigh his breakfast, work out the insulin, knows when he should and shouldn't eat and the best way to handle himself (mainly through trial and error but over time you learn what works and what doesn't).
So far it hasn't stopped him doing anything, perhaps me and his dad are there more than other parents - always get first dibs on the school trips etc but he still does football tournaments with school, if we can't be there the school work something out and all the staff are trained (office, teachers and TA's) as he's getting old it's easier.
I would like to say there's no chance of a sibling getting it but unfortunately for us his younger brother was diagnosed 6 months after him at age 5, again he has been okay, I think seeing his brother deal with it helped him and he did injections almost straight away, they are both quite different in how good effects them but all the snacks and carb counting isn't much worse for 1 than 2. We didn't do trial net just kept an eye out for signs (he was drinking loads so we used his brothers blood tester) we also
Have a little girl and occasionally test her but so far so good.
Our middle son started a pump recently - it has been amazing tbh and wish we had done it sooner, much better control, no time limits/ less of a routine needed with the food and obviously no injections. Our eldest is still on injections but has now changed his mind so we are waiting for funding to go through to start him on one in the next couple of months hopefully.
There is a great Facebook page

Which I found invaluable in the first stages, we also tried to make it fun for the boys with smiggle case for their equipment and a nice backpack that they got to choose.
You will also be entitled to DLA - you cannot claim until 3 months after diagnosis/ first symptoms - the form is quite long but the extra money means we can treat the boys to extra bits they wouldn't normally have and also helped for all the extra snacks and foods they need as I found our food shopping went up by quite a bit!
Any questions please ask as always happy to talk, our hospital also did a Christmas type party and that was a really nice event to meet local parents who were in the same situation and we see a couple regularly!
We are in Surrey if that's nowhere near you!
