Struggling with gestational diabetes

Anyone just get diagnosed with gestational diabetes and having a hard time eating only certain foods? I just got diagnosed less then a week ago, on and off it’s been a roller coaster with trying my best to eat the best I can. Thankfully my sugars weren’t too high. Few points off. I’ve been also checking my sugars an most the time they are good/ok. I forgot a few times to check it. Please no negative comments, as I’m trying hard. I’m having a rough day an not eating too good, nothing terrible but I know it’s not good for my sugars. Ugh.
