Learning english to be fluent is not a piece of cake.
Dont get depressed even you feel isolation from this english community. I would like you to try to think that learning english is a kind of investment for your life business. Stop using our han-gul. 한글 is the best and most scientific language but people are not interested in our language as much as we believed.
Please remind of my word, Learning english is a kind of investment for you as international student. Just break and smash your thing that makes you down.
한국어하는 나로서도 영어는 투자이고 배움에서 맨땅에 헤딩하며 배워가는게 영어에요..
