Honestly it's not that bad I've been gf about 15 years and my mum for 35. It used to be shit as no one knew what it meant now so many places cater for it and understand it.
I avoid most GF replacements and instead eat things like brown rice, quinoa, potatoes, buckwheat, sweet potato etc
. I can tolerate gf oats so have porridge with chia seeds, walnuts and blueberries for breakfast or Greek yoghurt and fruit.
I have salad with a massive mix of things (anything of lettuce, watercress, rocket, spinach, boiled eggs, avocado, peppers, carrots, tomatoes, feta, mozzarella, blue cheese, roasted nuts and seeds, artichokes, beetroot etc) or brown rice with chickpeas, spinach, feta. Or an omlete with mushrooms and cheese.
Dinner usually rice and veg chilli orr jackets, pad Thai with rice noodles, veg and tofu, Shepard's pie with lentils instead of lamb. There's millions of recipes online.
GF cakes can be great especially if moist (BBC rhubarb and custard cake, just use GF flour works, brownies are the same...)
You will get there.
