Sick of the diet

I'm sick of having to eat what I do to maintain blood sugar levels. It's so frustrating. I've had gestational diabetes since week 17 so this pregnancy is dragging. I just want a brownie or a cookie without worrying or feeling bad. I don't eat those things right now but dammit it's Christmas time. People waving treats at your face while you eat your boiled eggs and cheese. Ugh 😑
