My friend keeps talking to me and saying her older sister abuses her. I've even seen her do it when we're calling, and it seems she doesn't care. I want to do something so that she'd stop cause she comes to school with faint bruises on her arms. Her older sister keeps going out with friends, and her dad isn't doing well; he's very sick and is struggling. She goes out without telling him, and most of the time, she doesn't have anyone to pick her up, so he has to drive despite being sick. She doesn't even contribute or help him with his medication. She talks back to him, mind you, she's still in grade 12. When he yells at her, she acts as if she doesn't care and still does it. I genuinely want it to stop at this point cause I feel bad for my friend. I don't care at this point. I have tried everything and convinced my friend. I talked to her, helped her when she vents. It's not getting any better for her. Can anyone help??
