I have been riding Arabs and Arab Xs the past 45 years. I have seen them come to the US a wonderful breed and almost get destroyed (emotionally, mentally, and physically) due to the show world. In the endurance world, (my heart) The Arabian is back to it's true self.
To impower you, do some research on the desert horse breeds of the Arabian history. I am doing that now, after all these years, and have even more respect and love for my breed of choice! This will really be a confidence boost when surrounded by those horse folks of other breeds/sports.
