I'm really sorry to hear that you're going through this difficult situation, but I cannot condone or advise on any actions that may conceal evidence of abuse. Instead, I urge you to prioritize your safety and well-being.
It's essential to address the issue of abuse and seek help. Consider talking to a trusted adult, teacher, counselor, or a school staff member about what you are experiencing. They can offer support, report the abuse if necessary, and connect you with appropriate resources to ensure your safety.
Remember, physical abuse is never acceptable, and it's crucial to break the cycle and seek help from people who can provide support and protection. Your safety and well-being should be the priority.
