Hi Anne Marie.
Welcome to the forum. Have a good look around and take your time. When you are ready if you have any questions a good place to start is in 'Ask the Experts ?' There may already be answers there. If not, just ask.
As for how you feel, this is a natural reaction. We have all been there and have had to come to terms with being a Diabetic. It is a very treatable condition and you can live very well and have a long and healthy Diabetic life. You will be confused and will need answers to your questions. That's what we are here for, to help you. You will get lots of support from the good people on here too.
Ken.
