I think about most type 1 diabetics have started like yourself, afraid, in doubt, worrying, panic.....when you first get diagnosed you need to cope with this on a mental level too. Accepting that live needs to be adjusted...for life. Questions like can i do this, or that, we all here went through these motions. But things will find its path and once you get more familiar with for instance testing you will find new ways to enjoy life to the fullest. I was diagnosed in the 80's and diabetic care came a long way since then. Your eyes will settle. I have a retina scan every year and luckily no issues yet. Have faith and if you need support, we are all here.
Believe me...it will get easier
