I totally get that. Even here in the US it is hard not to get a little dairy or eggs in your meals on occasion, and that's with no language barrier! I respect anyone who does the best they can, especially if what you are consuming is all locally sourced.
I originally made the switch after researching the health benefits of eating a plant-based diet. I read a lot of books and starting watching documentaries and was sold on it being the most ideal way of eating for the least amount of disease and inflammation. I actually noticed a big difference in my sport recovery when I cut out animal products. As I started getting further into the lifestyle, I learned more about the ethical and environmental impacts, as well. I've always loved animals, so once I related that love to the food on my plate I could no longer consciously choose meat for nourishment. It definitely took a while to get the right balance and really make sure I was eating enough to support my active lifestyle. Once I started experimenting more in the kitchen and getting my meal plan right, I felt great and had no reason not to keep on eating this way! My boyfriend still eats the occasional eggs and cheese, and very rarely some meat or fish, but he feels better having switched to a much more predominantly plant-based diet, as well.
