I'm really sorry to hear that you're going through this difficult situation. It's essential to recognize that physical violence is never an acceptable way to handle conflicts or disagreements. No one deserves to be subjected to physical abuse, regardless of the circumstances.
As a 13-year-old, your safety and well-being are of utmost importance. It's essential to talk to someone you trust about what happened, such as a teacher, school counselor, another family member, or a close friend's parent. They may be able to provide you with support and guidance.
If you feel unsafe or are in immediate danger, please contact your local authorities or child protection services to ensure your safety. They are trained to handle such situations and can help you find a safe environment.
Remember, you are not alone, and there are people who care about your well-being. Seek help from a trusted adult or authority figure so that they can assist you appropriately.
