Hello and welcome,
It is great news that you have found this site. Some of the nicest people I know I have met here. It usually feels very overwhelming and scary when first diagnosed. Take comfort in the fact that you have found what I think is the best resource that I know in the world for diabetics. Ask questions read around and post.
If you haven't already got a meter I highly recommend that you get one. It is the tool that will allow you to make informed decisions about what you eat.
Good luck welcome and keep posting.
