Don't hold your breath for a cure. There is a lot of talk about it, and once you find you have diabetes, its like what happens when you buy a new car. Everywhere you look, you see your car. Even TV commercials seem to all be about diabetes now, even tho I scarcely noticed them before I was diagnosed.
What advantage there is today, is meters, and a lot of information to help you control it. Pre-internet, there was good cause to freak out because there was no way to share information, and support each other, so everyone goose-stepped to the ADA, with no way to get real life information.
Get the meter, and test, test, test, and then eat to your meter, no matter what anyone tells you otherwise. There is no "diabetic diet" Its very personsal. Its low carb, of course, but what sends my numbers screaming, may have very little effect on yours. Therefore, be careful with what you eat, don't be fooled by products labeled "low carb," don't buy into the notion that you can have X amount of carbs per day. You have to find out how many carbs you can have, and your meter will help you get there.
I might add that there is panic, and fear, and anger, and all sorts of emotions, but try to remember one thing. You are not going to die from this tomorrow, or next week, or even next month. You have time to sort it out, experiment, start a food journal, and come up with a plan for what you can and cannot eat, basically for the rest of your life. Moderation, and common sense are better tools than what most doctors offer as advice. Plus, remember that stress raises glucose levels, so live life, relax, and just make the changes as soon as you can, without freaking yourself out.
Also, you didn't become a diabetic from over eating. That is an out and out lie that the medical profession continues to propagate. You see, they will run around screaming that 70% of America is overweight, but don't see the ignorance in that statement, as it relates to crying "over weight people get diabetes" Since 70% of Americans don't have diabetes, well duh! Its a factor, you bet, but thin people get diabetes, average weight people do as well.
Your journey begins

Read, apply logic, relax, and give yourself some credit for having chosen to do the right thing and work through this. Forget the "research" about heart disease, kidney failure, and whatever. You cannot change any of that. What you can do is lose the weight, eat low carb as possible, exercise, and test, test, test until you learn what is good for your numbers, and what sets them off.
Remember that 'carb' is a buzzword for starch, which might help you see that most white things are bad, and even any kind of grain is probably a bad thing. Start with as few carbs as you possibly can, to get the numbers to start to dive and make you feel better about things. Then add a little at a time, one food at a time, and watch the meter.
CalorieKing - Diet and weight loss. Calorie Counter and more is a good resource for nutritional information on just about everything.
That's enough. Go for the tests, listen to your counselor, and let us know what they tell you. With respect, almost everyone I have ever read who reports on what their counselor tells them to eat, has been completely wrong. Even the ADA is up in the night about how much you can eat, and how to control your disease
Take ownership of your disease, and be responsible for what you do with it. Even if your dietician or whomever is a diabetic, chances are, what's good for him/her, may well not fit for you.
Hang tuff.
