It sounds like you have,much more problems with your endrocrine system than just having Diabetes. Ask for a referal to Endrocronologist or Internist. They will check all of your body systems and tell you what else is going on with you. If you have no willpower and cant exercise, perhaps considering a lap band surgery will help, as at your age it is increasingly dangerous to be overweight, let alone the diabetic status as well. Lap band surgery will cut the size of your stomach and therefore you wont be able to eat as much as you want and then lose weight. However, this should only be considered if you absolutely cant lose weight through diet and exercise.
