When you enter high school, it is completely normal to want to be part of a group. However, you have to keep in mind that there are more important things, especially being yourself. Since it is your first year, there will be many people who you want to be friends with, but you have to keep in mind that the people you want to be friends with are not always the best choice. Try to make friends who you do not have to impress to be accepted. Make friends who accept you as you are.
It is crucial to keep in mind that sometimes being different actually gives you advantages in different aspects. Even if someone singles you out and makes fun of you for your differences, you should not let it bring you down.
