I have an excellent relationship with my children so of course I'd let them know of any diagnosis I have. I agree with what was posted above, no "playing the victim."
Patnono, you keep posting about your lack of support regarding your diabetes. Start your own online research, go to the library and get books, EDUCATE YOURSELF. There are excellent diabetes forums and other people are very willing to help... but you have to help yourself. The most basic steps you can take are to get some kind of physical activity, adjust your diet reducing carbs, and monitor your glucose levels by testing. If you will just get in the mindset that diabetes can be managed with a little effort on your part it will make a world of difference.
If you aren't willing to take care of yourself, no one else is going to. If you have a difficult time with diet, start by cutting out all WHITE foods... no flour, sugar, rice, potatoes, bread, etc. Focus on lean protein and vegetables, occasional fruit, and whole grains. Your glucose monitor is your friend; learn to use it. Get up and WALK. This is not rocket science; it's your life.
