Why dont you try thinking less often about yourself and more about other people? I would think everyone is in pretty much the same spot as you, strangers in a strange land. Im only saying this because this post sounds like I could have written it. When I took a Dale Carnegie course, I was like, why am I not getting an award? Im a better speaker than anyone else here! The week that I finally acknowledged there were other humans in the room worthy of my love and consideration was the week I finally got my award. It feels to me like you need to "see" the other people and worry more about them than yourself.
