Gestational diabetes

I’m having such a hard time sticking to a strict gestational diabetes diet!! I’m also on extremely strict bed rest so my family/husband are cooking literally breakfast lunch and dinner for me.. I can’t grocery shop on my own or do any meal prep on my own and they don’t really understand the diet. I just feel like I’m failing. I’m 30 weeks and just feel so ready for this to be over. I really was hoping I could enjoy this pregnancy but it feels like I’m failing at it all and I just want to cry..
