Feeling frustrated

I was told four different times by four different people at my OB/midwives office that I did not need to fast for the glucose test. I had my normal breakfast that morning (about an hour and a half before my glucose test) I had half a blueberry muffin, a banana, a whole bunch of watermelon and strawberries, an egg with a slice of toast, and some orange juice. After I finished I drank the solution and headed in. When I got there the Phlebotomist asked if I had been fasting for at least 14 hours. I immediately started panicking because I told her no I literally just had breakfast and she said they’ll do the test and just tell my doctor and they’ll let me re-do it. Unsurprisingly I failed and when I tried to tell my doctors office that they said “it doesn’t matter you have GD and you’re seeing the diabetic clinic now” In the two weeks I’ve been monitoring my glucose levels, I’ve only had two readings above the normal range. And it only happens after my “bedtime” snacks. I’ve told them that having to eat before bedtime makes me so nauseous and I always end up throwing up and it always makes my blood sugar levels go up. I’ve tried telling them that I can’t do the bedtime snack because it makes me sick and my doctor basically said “it’s not the food you’re eating it’s your body because you have gestational diabetes” The nights I haven’t had the bedtime snack my levels were perfect.

I went in today for my OB appointment to talk about how I feel I was wrongly diagnosed and my feelings / what’s been going on. The OB I saw was alarmed because I’ve lost 10 pounds in the last 2 weeks. I tried to tell them the only thing that’s changed is the meal plan the diabetic clinic has me on. My OB was more concerned about my weight loss, that I couldn’t even get in the GD diagnosis. They want me to up the amount of food I’m eating / increase my protein and carbs but that’s literally the exact opposite of what my diabetic clinic is saying. I’m so frustrated I just sit and cry all day. We tried for almost 4 years and I was so excited and happy since we found out and since this diagnosis I’ve just been miserable and angry.. I’m just looking to vent and maybe see if anyone has any advice.
