Jack the bully

you are a girl who goes to school, but because you've had such a terrible life (you're father died and your mother was left to take care of you, but passed from a sickness when you were old enough to take care of yourself, your house burnt down 3 times in your whole life and you've suffered a lot of bullying) the gods have finally rewarded you for your pain, you are capable of bending a material (stone, dirt, water, air, gold, wood or etc), but only one (you choose it). jack is the school bully and he has bullied you many times.
