Having a hard time eating enough

Hello! I was diagnosed with GD a week ago and I recently started tracking my blood sugar. I'm someone who has never eaten breakfast, I usually don't get hungry until around 1 or 2. I know I'm supposed to eat in the morning but I feel so full I can't even stomach the thought of food. Especially now that I'm eating so much protein I wake up still feeling full. And it's not like I'm eating too much. For context, I have a higher BMI and my regular calorie intake when I'm not pregnant is around 2000 cal/day. In the last week I've tracked between 1500 and 1800 calories and roughly 150 g of carbs per day usually. My dietician recommends 3 meals per day and 2 - 3 snacks per day but I feel like I just can't keep eating to the point it's making me uncomfortable. I have another meeting upcoming with the dietician but I'm wondering if anyone has tips?
