Struggling with Turkish home cooked meals

I'm probably the only person in the history of Turkish subreddits to complain about Turkish cuisine, but I'm really struggling guys. Everytime I visit Turkey with my partner and we stay at his parents, the first days are fine. I like their cooking, it's an interesting excursion for my palette, I complement my mother in law. But after a few days, I'm so done with it. It all tastes sour, my stomach is protesting, and my body basically prefer to go on hunger strike than to have yaprak sarma or any of the million peynir that all taste the same to me. Breakfast, lunch, dinner, I struggle. Is this something you notice foreigners have problems with? (I'm northern European) Is it the dairy that has typical bacteria that I'm not able to process well? Although I don't know if it's only the cheese and yoghurt... I also had the same difficulties yesterday when we had artichoke hearts and okra, which I could process much better at the start of the trip...

I'm also at the point of my body protesting to eat so much that I can't even conceive of what food I DO want to eat so I can cook it instead. I tried to cook myself an egg today but the butter( from his parents village) made it weird so I had to force it in. I've been sneakily eating leftovers of rice to feel full enough.

I really really hate being a fussy eater and I wish I could appreciate their efforts but I can't really hide it anymore that I'm not enjoying the food. I'm awake now because my stomach hurts, and I have another 2 weeks to go... Any advice or consolation would be greatly appreciated!
