Well Lilibet, the left brain and the right one are still arguing, at least you have a brain which is more than can be said for me....
Look its all normal, to feel like this and dont beat yourself up over it, you are in a state of shock, so are your family, everyone is worried because most of us only ever hear of the results of diabetes complications, the negative side of things. Of course it is unfair that you get diabetes, its unfair that I have it, its not fair on anyone at all, we know we have to deal with it, but its not so easy,not in the beginning, you get all the facts and advice and some of it coming from the professionals is actually outdated and downright dangerous in some cases and you feel like you are wading some really dark woods all on your own. Its not just physical effects, its mentally too, depression, confusion, anxiety, fear for the future, all the what ifs and so on, these things play a big role too and its often overlooked.
Go with the flow, dont hold back, crying, ranting, raving, dont bottle things up or else stress levels can have a profound effect on bg levels too, you dont want that happening, I know part of your brain wont believe me that when I tell you that it will all get better, much,much better actually.
Pamper yourself, have a nice long soak in the bath with your favourite bubble bath or shower gel or whatever, treat yourself to a bunch of flowers, anything to make you feel better.
Yes you do right to drink plenty of water if you show ketones, take your readings, keep an eye on things, is the best you can do, testing and adjusting your dose, and learn about the condition, you are on the right track there already. I wish I had been as sensible as you are at the time of my diagnosis.
Love
