Can someone please edit my host family introduction letter. It is supposed to be formal


Dear host family and instructors,
My name is Amna. I am so touched to apply for this program. I'm from a suburban city in the United States, located in the state of Maryland. I live with my family. I’m constantly doing schoolwork at home, at the library, or at one of my favorite cafes. My family sees me as a responsible, determined, and dynamic person who works non-stop. My friends see me as someone stubborn, honest, and who loves to joke around. I have a more serious relationship with my family and a more pleasant one with my friends. My relationship with my family is complex, but whose isn't? I have an immigrant family, so I have to take a leadership role in my family to help guide my siblings and parents. I seek advice only when I can't find a solution. It's more of a last resort to me, but I always cherish any help I get. My friends come and go, they are important, but my number one priority has always been school.
I enjoy being a part of the community. I'm a reserved person, but I still see contributing to your community as necessary; it can help you become comfortable with others. I like working alone, but in group school projects, I make sure the work is divided equally. I am also a manager of our school's tennis team, responsible for sending out emails, setting up meetings, making schedules, etc.
I’ve made sure to recognize challenges I have to overcome. I'm starting to practice my Korean skills. I know it’s not guaranteed that I will get in, but it will benefit me in the long run if I prepare well. I’ve made sure my parents are comfortable with this; we've talked and ensured that we're all on the same page. When I was choosing the country I was interested in, I made sure to pick a place that I knew would challenge me, give me a good experience, and explore new cultures.
I aspire to become an aerospace engineer; my love for building stuff started with legos then expanded to rockets. I have to do the best I possibly can as a student, a sister, and a daughter so that I can be in a comfortable place where I can be eligible to apply for good colleges. I want a secure future for my family and me. My mother went to law school but could never work after getting married, and my dad didn't even go to college. I want to be the first person in the family to graduate college and get a job with my degree. I want to buy a house, each of my siblings would have their own room, and my mom would have her dream kitchen.
I also want to make myself proud. After challenging myself for such a prolonged time I deserve to be rewarded too and I'll do that by providing myself with opportunities I was unable to have before.
