12 year old girl looking to audition for a small part.

I am a 12 years old female, and I live in IL. I love to act, sing, and dance. I would really love to be in a movie or tv show!!!! It has always been to be a actress/singer. And everyone tells me that it will never happen, but that never tells me that it won't and i wont get any auditions. I will always believe that I can and will get auditions sooner or later. I woud really love it if you will make my dream come true! thanx so much! Also I would also like auditions only close to the Chicago, IL area, thanx so much!
