I think if you love basketball, you should be able to play it. As for the kid, try as much as possible to ignore him or her whenever he or she attacks you, after which she will see that she does not affect you. Concentrate more on what you can do and prove her and others wrong.
Victoria. Play ball! Life is full of people who try to bully you. Bullies have no super powers. They don't control you. Just hold your head up high and walk on. Not reacting to bullies saved me in three different high schools, so it wasn't just a coincidence. Go dunk one, girl!
