Yeah but that is why you prepare lol. You could have spend two months 2-3 hours a day studying, before moving and it would have been easier, given it is much easier learning a language speaking to a fluent person, still there is a fair bit you could have learned and not go over there blindly. Your friends are too blame unfortunately
Dutch is about the 4th easiest language to learn, stupidly easy compared to Afrikaans, which has significantly more complex language rules, both dutch and Afrikaans is conjunctive which would be a breeze, unlike English which is disjunctive and they would have a slightly harder IU time learning it.
Dutch doesn't have grammatical cases either and rules are pretty simple the only real issue is the word order.
