I can relate to how you're feeling very well. Some of my family members don't take the time to educate themselves about this disease. I get comments like that all the time, some even that literally make me want to cry. I used to be called the "worlds worst diabetic", it was awful. I used to stay silent to the comments and it would build up and cause me so much stress and pain. I've been able to stand up for myself a few times and the comments would stop for quite awhile. My suggestion to you is to keep your head held high and remind yourself that you are doing the best you possibly can in an impossible situation, they will never be as strong as you are. We all deserve that slice (or two) of cake because we know how to take care of ourselves and dose accordingly, even if we screw up and eat way more snack, candy, and cake than we planned too, we are the ones who take care of ourselves and stay up all night checking our keystones and waiting for the sugar to go down, waiting to feel normal again. Don't ever let anyone make you feel inferior or incapable. You can do this, I can do this, and we can do this, together.
