This is so me! It's terribly exhausting to the point that I'm totally drained after going out or doing any kind of interactions (especially speaking the language that's used where I live). Even though I know the language I can't speak it fluently due to my blocks and it isn't easy navigating life. Saying my name is also the main problem along with others. I want to come out of this but what can I do if I can't get those words out and like you I too can get away without making it obvious. I feel you. Stay strong is all I can say mate.
