Welcome MamaRuth, there is a sparkspeople cookbook that has a special section on how to adjust your foods for diabetes. There is a great support system for diabetics, from a total diabetes tracking system and diet recommendations.
you can find a lot more about sparks in the "Getting Started Guide" that shares all things Sparks. You will also find a huge support system for people who are in the same situation you are in.
Utilized the guide to learn your way around sparks and get yourself started, then start using the cook book to help you adopt yummy recipes that will meet your needs and their as well.
if they are living with you, they should be supportive of what you need to do to keep your disease in check, and their are great suggestions on the teams/message boards as well from Chef Meg.
be authentically you...
it's journey, not a one day hike.
