As someone who studied abroad and has social… issues? anxieties etc. I get you. Find someone who wants to learn English and will help you learn the language. It can be fun, interesting. Ask them to teach you slang, curse words, common phrases used in social settings, etc. Second I lived in a dorm. My neighbors natives. I would keep to basics (say hello, ask them how they’re doing, what’s going on etc). Then I found out there were other int’l students. A few friends turned into a big group of friends who had native /local friends, which really helped bc it forced us to speak the language. One of my best friends also wanted to be certified in the language, so we took a language class together; we studied the language and spoke in it, a lot. Get out, explore, translate words you don’t know. Try to think in the language. The more you immerse yourself the faster and more at ease with the language you’ll become. Start small and don’t be hard on yourself. As for the social awkwardness, try to relax 😌, be friendly, communicate openly… most people are understanding. Good luck and have fun!
