Traveling to the United States for only one year

Yup, guys! I'll travel to the USA tomorrow and well is only because I need to learn more English, my mom said:
''This Is A Big Chance To Learn More, A Lot Of People Can't Travel To USA, But You Can Do It''
*Sigh* Well... I think she is right, but I'm really nevers, I never do this, I never told you this guys but I'm not Mexican! I just live here, I was born in the USA, I leave the United States when I was 4 years old.
The crazy thing is... I never studied at an American High School, and well you know... New Teachers, New Classroom, New Subjects, New Crazy Guys and Me, The New Student! :3 hehehe.
People will say: ''Hi! What's Your Name?'' And I'll say: ''Oh... Hehehe Hi... Hi..., Do You Like Danny Phantom?'' X'DDDDD
AHHHHHHHHHHHHHHHHHHHHHHHH!!! What I'll do?! I never talk with a real American hahaha :'3
Well... I hope nothing BAD happens, I'll upload some pictures of my new High School if you guys want

Good Bye!    Wish Me Good Luck!
