I need some very helpful advice- on acting?

Hi, my name is Yasmine. I am a 5' 3" girl, and i weigh 99 lbs. I have tan skin, and I am mixed. My dad is from Bangladesh and my mom is American/Iranian, so my skin is mixed. I'm 13, and my lifelong dream has been to act. I have auditioned for my local theater and got the lead role, I obviously do acting cles in school, I have gone to acting camps, and I can also sing. I love to sing, but acting is my pion. People say I am very good at acting, and that when they see me act it is as if I am not "acting" the part, but I am BEING the part. I live in Pittsburgh, Pennsylvania, which I know isn't the spotlight of acting, but New York City is about 4 hours away from where I live, and my family is willing to go anywhere to help me fulfill my goal. I want to be reconized as an actor. I want to be showed in movies and/or TV shows, for Hollywood. I understand this is a big goal, but it is my DREAM. I don't think anyone knows how much I spend almost crying knowing that this will be so impossible. I just need someone to help me. I need someone to give me good advice on how to make this happen. Thank you!:) Also, if you say I need an acting agent, then how do I get one? I luv anyone who gives me a good answer on this! Please help me!
