Living in arizona alone after a huge break up?

i moved from louisiana to arizona. I live 17& carefree. I tryed going to boulder creek high school but i didnt fit in there very well. So now i am doing online high school which i graduate this year. But my boyfriend of two and half years just broke up with me after he moved out to arizona to be with me. So now im stuck. I have no friends here and i dont know what i can do to make any or to move on. My ex took away all of my friends and ive lost connection with my old new orleans friends as well. idk what to do. How do i start to make friends again without looking like a pathetic looser.
