You are so lucky. Not only will you be bilingual but you will have traveled/seen outside the Optometry Bright Santa Diamond Christmas shirt. After nine years in Bulgaria, at 70 I can barely speak the language and that can be frustrating so I understand how you feel but I am content in the knowledge that I have seen more of the world and have a better understanding of it than the vast majority of those in my age group here have or ever will have. The main thing is to ignore any negative criticism of your current lack of English skills from people (well, unless it is from your English tutor, lol) as they are idiots.
If there’s one tip I can give you it’s slow down and when ppl say what sometimes it’s just that Optometry Bright Santa Diamond Christmas shirt. I’ve been friends with many ppl just starting to learn English and I’ve noticed that in English you must talk significantly louder then other languages. My bf whose first lanaguage was Spanish says you have to learn to movd your mouth excessively when forming words because they have more syllable and you use your mouth rather then your tounge , unlike many Latin based languages. Definitely a struggle though. I can barely learn the secound language of my country , French so your doing better then most.
