Moving to a city and new school!😬😬😬(help)

So hopefully after this Corona virus thing is over I’m planning to move out of my small town and into a big city and go to a huge school. I’m pretty nervous. I’m only 15 so this is going to be a big change and I thought you powerful, amazing women could help me out. So I currently live in a town with around a thousand people in it and I go to a school that ranges from prep to year 12, it only has roughly 122 students in it. If you think that’s small, well, my year 9 class is only 3 other people. So I’m moving because I know it will be better for my education and future life. I will be

moving up with my grandparents and my big sister. Hopefully I will get into the same school as my sister!🤞 Which should make things easier. I know it’s still a while off but I thought I would ask for your advice on it. Have you ever moved schools or place? What was your experience like? Got any tips? Anything would be great to hear! Thank you! ❤️❤️❤️😊
