Those who love you the most

What was I thinking when I accepted to do this school exchange? 6 months in Palos Verdes in USa, with a host I know nothing about except her name, Jenna Hamilton, in a high school I've only seen a picture of, Palos Hills High School. What am I gonna do of the next 6 months! (Rated T for language even if i'm not sure if it will be necessary. And sorry for the mistakes)
