I just want a damn sandwich

Literally anything other than tuna salad and carrots AGAIN. Who the hell thinks it’s ok to make rye bread with 30g carbs per slice?? I just want a Reuben, but without the bread it’s pointless. I hate this stupid diet. I can’t eat anything. I’m already on medication and I still can’t eat anything. Does anyone know why they seem to think it’s normal to make the blood sugar limit 140 for a pregnant woman, when for a normal person it’s 180 after meals? Why would they lower it for someone who’s supposed to be eating more food?? I’m sorry for the ranting. It’s a hard day.
