What do I have to answer when someone asks "What's Up?" It's to tell if I'm good or tell what I'm doing?

Qualcuno mi può mostrare alcuni film italiani? Can someone show me some italian movies? Proprio per aiutarmi a capire.

Una notte in ospedale Ieri ho dovuto andare in ospedale perché si sentiva un sacco di dolore, ho dovuto prendere iniezione e ottenere quasi tutta la mattina lì. La mia schiena fa male, come mi era stato investito da un autobus. Io odio gli ospedali!

Moving out All started when my dad died and I stay alone with my mom here, my family is from Italy, they live in Palermo, so I'm going to move out to there. I don't now much about Italy routines, I've lived with my italian grandparents here in Brazil (in a country side of Minas Gerais) but it's not the same thing as living in Italy, maybe I'll never see my friends again and if I don't like Italy? I'm going to be alone there because I don't speak italian so good. So many doubts :(

Studying with videogames Is so good and easy to learn a language just playing a game, when I was learning english the games have taught me with they histories and so about culture. Now I am learning about italian and again a game (Assassin's Creed II)  have helped me about a lot of things.
