I also just wanted to add that the Low FODMAP diet is not for everyone, so if it doesn't work, you really don't have to force yourself to follow it! Maybe keeping a food journal might be a better idea for you? We have a free one you can download here: https://irritablebowelsyndrome.net/living/food-journal-download. We're all so different, and sometimes foods that are safe for many people don't work and supposedly "unsafe" foods can be fine. For me, dairy is often okay, but pumpkins and squashes make me very sick, even though they're supposed to be safe, for example.
Wishing you all the best,
