Take care of your items, friendships, and things that you love!
Jesus only speaks in the hearts of believers. If you are not saved and want to become a Christian, then ask your parents or a Christian adult you know to explain how.
The next time that someone is mean to you because you are different, or refuse to act like them, remember that God made you unique.
Listen to Paul and set an example for other believers. There are so many ways in which to do this, no matter how young you are.
