Hi Debbie, welcome to the forum. The diagnosis of diabetes can hit one hard, finding out quickly which type of diabetes you have will help you sort out the best approach to it.
There are no daft questions, just ask anything you like. Its a learning curve that goes on, I been diabetic for 13 years and I am still learning as things change.
There will be a lot of stuff to take in when diagnosed, and depending on your GP / post code will depend on the support you will get.
A few important things to get sorted are to check you get on the annual hospital eye screening programme, the annual foot screening programme. As you are on meds for the diabetes you are entitled to free prescriptions and eye tests at the opticians. You will need to get a couple of forms from your GP which the GP will need to sign and then take / send to the relevant places.
The next one is down to the post code lottery / GP practice and type of diabetes and varies all over the place and some times in the same GP's practice. Its worth getting hold of a glucose meter, which you can normally get free from the likes of Abbott medisense, Bayer, Life scan, Accu Chek to name a few.
Have a look at the meter providers web sites and see what around then give them a ring to see if they will send you one free. Every one will have a preference of which meter they use, I use the Bayer contour usb and the Accu Chek mobile for different reasons. The problem is that for some the GP's won't provide prescriptions for the meters due to the cost.
A meter is valuable in identifying what foods do to you and which foods are to be avoided or taken with care. Some foods effect people in different ways, white bread or foods made with white flour tend to send sugar levels sky high with most of us. Other foods like bananas affect us in different ways, I am ok with them for others it rises their sugar levels to much.
