Well I've had T1 now for 40 years and can well remember that scared feeling. I remembered it last year when I first had my pump - I'd got over the original lot by then! - but pumping was so, so different to what I'd known ever before, I had trouble with it, same as I did in 1972.
My advice? - go with the flow. When you feel like going and having a cry, go and have one. Obviously not if you are just walking across a tightrope but then, I found it was more when my mind wandered, not when I was otherwise concentrating.
Try reading a book to occupy your mind. The book I would very much suggest you read is this one
Type 1 diabetes in children, adolescents and young adults
by Ragnar Hanas.
It's good reading for anyone with T1 even if you are old and crusty LOL and it isn't as 'science textbooky' as some of em.
The more you can learn about your diabetes, the less you will fear it. Honest !
Good luck.
