what should I do?

when i was a college student, i also found myself difficult to communicate with my foreign lecturers. and since i studied english to become a teacher myself, i should encourage myself to be braver and opened. at a chance outside the class, my first attempt was asking to borrow my foreign lecturer's magazines. it was very difficult for me but then i could manage it. you see, if we don't try even at a first try, you won't be able to communicate with them ever. people said, the first one is the hardest, the next will be easier. keep this in mind, and keep trying! good luck :)
