As Fergus says its bewildering at first, not least getting over the idea that you have type 1 (which I always thought only children got) I was diagnosed almost 4 years ago and remember being in a daze for much of the first few days in hospital. I was lucky though to have quite a lot of 'education' .
When I came out of hospital I had been told to eat regular meals. That is at regular times and with a fixed amount of carbohydrate in each meal. I wasn't too happy about it as I had an irregular lifestyle but it did enable me to learn to adjust my bolus and basal insulin according to my BG. I was told to test several times a day (fasting and 2 hours after breakfast, before and 2 hours after lunch and dinner and at bedtime, also before, during and after exercise ). Being consistant with the amount of carbs enabled me to get a grasp on what my body was doing and importantly just exactly how much insulin I needed for every 10 grams of carbohydrate.. As you will hear often, we all vary. I can now be far more flexible with both timing and amount.
The number of carbs you 'need' will depend upon your body, your ideal weight and your lifestyle. If you were not given any indication of the number, I would hope that someone at least suggested the type of meals appropriate for you or that you see the dietitian soon.
To work out the carbs contained in your meals you need to get hold of a book of nutrition tables as sold for dieters Try to get one that gives the figures as carbs per 100gms it makes a calculator less necessary. For processed foods you can use the figures on the packets. Use digital scales to weigh foods rather than guess at first. Its particularly necessary with foods such as pasta, potatoes, rice and bread which are carb dense
Rather than try to describe insulin adjustment . I suggest you add to your reading list and read this excellent page about how basal/bolus regimes work complete with charts on adjusting insulin according to results here.

Its quite detailed so it needs very careful reading. As it is from an NHS source I would think that its methods would be acceptable,
however, if you decide to try it , you should check with your doctor or nurse that this method would be appropriate for you (particularly that they agree with the amounts suggested for lowering, raising insulin for differing BG leves)
Thats enough, probably too much and probaly too diadatic (sorry!) As others say it does get easier, honestly it does.
