I would start by getting a CD at a Best Buy or OfficeMax that teaches the basics of Italian.
You live in Chicago. Shoud be lots of people there who speak Italian if there is a neighborhood where Italian people tend to live. Might be able to find a way to make friends with someone around your age there who speaks both Italian and English.
See if there are any events coming up in the Chicagoland area concerning people of Italian descent. Attend and try to make friends with someone who has similar interests as you.
Maybe there is a student at the school you are attending who is from Italy? Possibly makes friends with that person?
The following sites may be of help to you. I hope that they are.
