She doesn't deserve the yelling. She already gets it. She tries her hardest. Why can't you get that? She is trying her hardest. She doesn't deserve to be sad. She already gets it and knows she messed up it's happened before. So don't yell at her. She knows what she is supposed to do and she will do it. Don't go yelling at her when you have done worse when you were in that situation. She knows she could fail. You don't have to yell at her and tell her that she is going to fail if she doesn't get her grade up. She already knows. So don't you dare think that you did better, because you didn't. And if u think you DID do better well, check again because you are wrong. You did worse than her. So don't yell at her. I know you want her to be successful and she will just not by you yelling at her. Not by you giving her lectures about what she already knows. You have to support her. At her toughest times, like right now. She will make it. I know she will. She's my sister. And she's my best friend. And I won't let you do that to her.
