Help me explain

I can't explain how tired I am of trying to explain to my husband that I'm doing what I'm doing because I have to. I'm 32 weeks pregnant and I have gestational diabetes. I am also on insulin. I have never been diabetic and wasn't with my first born but in this pregnancy I am. I have diabetics in my family and my husband also has diabetics in his family. I was clearly instructed on what i could and could not eat. I also have to eat 6 times a day, eating every 3 hours. I check my sugar 7 times a day and inject insulin 2 times a day. I do it all for our unborn child like i was directed to.

At first he believed i was starving myself (by no means are we fit and skinny people, but before pregnancy i weighed 192 lbs) because of the small portions I have to eat. But i used to eat only 2 times a day and pretty big portions, now things have changed. One of the things I am NOT allowed to eat are canned foods. Too much sodium and I was told I cannot.

Today, my husband asked what I wanted for lunch.

He usually cooks our meals and since I've started the diet and insulin he doesn't want to cook a "big meal" just for one person. I've explained millions of times that he can eat what he wants but I have to follow the diet. He offered me canned baked beans and I told him I couldn't eat that. It started an argument all over again on how I'm the only person he claims to "know" that cant eat canned things while being diabetic. That his aunt eats what she wants and she's diabetic with insulin. Yea, I have gestational diabetes. I want to take care of myself to not have this for the rest of my life. I do what I gotta do, why keep saying it's just me? He doesn't believe these restrictions have purpose and that I am truly the "only" person who is doing this. Any suggestions to help him understand that isn't the case?

To Marianna, I never said i was handicapped. I said he usually cooks lunch and the reason why is because he likes doing so. I love cooking my own lunch and have no problem doing it. I'm also not being dramatic. I'm following the directions from my dietary nurse and obgyn. Even with following the diet and being on insulin, eating the same breakfast some days my sugar is higher than others, reasons Idk but that's how my body is.

But thank you for the comment.
