I’m gonna share this as a personal experience, I just moved abroad too a little while ago (france) and despite I speak their language since I was 6 but it’s not the same, because of the lack of the practice for direct communication, but at the end of the day, the only solution was to go out and talk to people, I made mistakes, I couldn’t find some words but it’s still okay and they never made me feel embarrassed because they appreciated the fact that I’m trying to be better at speaking it
