Hello and welcome,
I am not surprised you feel nervous and afraid but the great Nes is that you have found this site. I was also nervous afraid and devastated when I was diagnosed- the amazing people here have made all the difference and will also be willing to help you.
If you can provide some more information then that will help people give you some guidance. The information that is most useful is what type of diabetes you have, your age, your symptoms, whether you are overweight or not- and don't be afraid of being judged- you won't get that here.
Read around and let us know how we can best help you.
Welcome!
