Hi Glen,
Welcome to our very exclusive club. We are very fussy whom we admit to the club. Don't Panic - Douglas Adams.
Everything will seem overwhelming, but we have managed to wrangle D, that I we have it for our convenience. It obeys me, well at least some of the time. Don't let it take over your life. For about the first year you need to follow your medical teams guidance. You will eventually work out what your limits are. You will even have a bit of fun. Even 20 years ago this was a nasty little affliction, now with all the electronic gadgetry CGM and pumps and them now being connected together, it's becoming one of the kewl diseases, you will have to wait a while and master the daily injections before you can think of pumps, CGM you can get right into now (it may cost a pretty penny, depending on a number of factors). For most of us here it's now more a lifestyle than anything else. You have every right to go through a grieving process. Especially to start with it may get you down and depressed, but things will get much better and a whole lot easier, in a few months time, you will wonder what all the fuss and panic was about. Most of us have been there done that, there are a few here that got it as babies, so they know no different.
