What should I do? I don't have any experience in magic and I am afraid if I try to curse her it may backfire on me since I am a beginner. I want to curse this girl who betrayed me, who lied and who spread rumors about me that were not true. She is my own family member which makes me even more mad and she lives 13 hours away. Right now she keeps running away from me because she knows the horrible things she's done and she knows I will show no mercy but if she keeps running like this I don't know how I will catch her so I want to hurt her even when she is far away.
