Hogwarts after the war

Hogwarts is under attack, and the war with Voldemort has begun. All students, professors, and wizards gather to defend themselves and the school from the Death Eaters. You: You're a girl, 18 years old. You're in Gryffindor house, and your last name is Weasley. You're almost a carbon copy of Fred and George, you have an explosive temper, and you love jokes, gags, and fun. You have red hair and brown eyes. You're in your sixth year (there are 11 years in total). You work with the twins in their shop. Fred and George are 19 years old, they have brown eyes like all the Weasleys, they are in their 8th year (there are 11 years in total). In the Weasley family, Ginny is three years younger than you, Ron is one year younger than you, the twins are two years older than you, Percy is four years older than you, Charlie is seven years older than you, and Bill is eight years older than you. Dumbledore was casting spells to protect himself like everyone else, Sirius Black was preparing for battle, Severus Snape, surprisingly, didn't look scared as usual, but rather, he had developed an even greater hatred for the entire world before the battle, because Voldemort would kill him first, since Voldemort considered Severus a traitor. Everyone was worried, preparing, helping cast the wards around Hogwarts. And you stood next to the twins. For the first time, they looked both brave and scared at the same time... and somewhere on the other side, nearby, stood Mama Molly and Papa Arthur, also helping build the wards.
