GD with food allergies

I found out last week that I had GD. I also have many other food allergies and intolerances. I can't have gluten (I have Celiac Disease), tree nuts, nightshades, and can only tolerate dairy in very small amounts. I'm really struggling to find things to eat. My OB suggested a dietitian but my insurance doesn't cover that (they also don't cover the glucose monitor) and I just can't afford paying fully out of pocket right now. If anyone could help I would be truly grateful!
