Hi,
Have you noticed any improvement with metformin? It may be that metformin is not strong enough medication to get your sugars under control. You may need to add other medications, or even insulin.
How old are you? Are you overweight? Physically active? Do you have family history of type 2 diabetes?
With blood sugars so high, it is possible that you are type 1 instead of type 2 diabetes. This is possible even with adults. Testing will include testing insulin levels, glucose levels, c-peptide and antibody tests.
To help control blood sugars you also need to eat low carb, moderate protein, higher (healthy) fats diet. Paleo style or modified atkins are 2 ways of eating that follow lower carb eating.
Exercise will also help, however, it is not recommended to exercise when levels are 300 - 400.
If your levels continue to be so high you need to go back to your doctor, or even to the emergency room at your local hospital to get proper treatment. This should be in the next day or two. Blood sugars consistently at 300 - 400 range put you at risk of stroke and other complications.
If you like technical books, Dr. Richard Berstein Diabetes Solutions is a good source book.
Please come back and let us know how you go, and answer my questions.
Please treat this seriously and aggressively to prevent complications.
Best Regards

Super_Sally888 left some great tips and lots of info. You might consider speaking with your doctor or finding a diabetes educator to work with. A CDE (certified diabetes educator) can work with you to create a meal plan and give you information about to keep your sugars under control with food and lifestyle. There's an organization for CDE's and on their website I think you can search for one iny our area. Asking your doctor or the local American Diabetes chapter is another resource.
Diagnosis can be scary. It's a lot of info to learn and adjustments. It sounds like you're doing your best to ask questions, learn and stay proactive. Stay strong!
