If you're reading this, you've probably just found out that you have Type 2 Diabetes. Sorry. I know just how hard it can be to come to terms with this, but you can at least take solace in knowing that you do not have Type 1 Diabetes. Type 1 Diabetics can not produce Insulin at all. As a type 2 Diabetic, you can at least produce a little Insulin to deal with carbs and sugar entering your body. This is actually fantastic news for you, because although you will need to make lifestyle changes to adapt to the diabetes (unless you want to be dependent on Metformin and Insulin until you die, which is OK too I guess...) you can allow yourself "weak" moments where you eat or do something that's not necessarily good for you, but won't result in your death at least. These weak moments can help strengthen your resolve for the harder ones. If you want the cold hard truth, to deal with your diabetes you're going to have to:
1. Prepare yourself to give up carbs and sugar. No more bagels, donuts, cupcakes, poptarts, or cakes for sure. IDEALLY you would also give up grains (they are a major source of problems in a diabetic diet and also turn into sugar as they are being processed).
2. Become best friends with the nearest treadmill or stairmaster. Exercise is an excellent way to lower blood glucose levels, and the more you exercise the more leeway you will have with your diet.
3. Join Diabetes community forums, such as diabetessupport.co.uk/boards/forumdisplay.php?f=12 . Such websites will provide you with an endless source of information and support for your condition. As questions pop up to your mind, you can get immediate answers from your new friends who will have personal experience in the disease. Note, that while doctors and nurses are generally helpful, it is in their vested interest to keep you on drugs (that's where their source of income is, after all). Just food for thought.
There are a lot of diabetes treatment programs available that can make this process a lot easier for you, I suggest looking into them.
Utilizing all these resources that are now availed to you, you can begin the first steps in tackling your Type 2 diabetes. The first day is the hardest, but you can come to find that once you've resolved to the necessary adjustments you have to make in order to fight your disease, it really isn't going to be that bad. Most of the changes that are being forced on you are actually going to drastically improve your quality of life. So fuck you diabetes, but at the same thank you (but still fuck you).
