I think your mom is abusing you and your sister. And your dad is just sitting around watching and he doesn't seem very responsible for anything. I suggest you talk to your school counselor again or your sisters school couseler and see what they think.
Think about all the ways you can help your sister to not become like you with all the problems and I hope you get better too :).
Go to the school councilor and tell them that your mother is being this way with your little sister. They will pull her from class and ask her questions. Tell your sister to be honest with them.
It's very important that you help protect your little sister. She needs you. I'm sorry to hear that all of this is going on.
It's NOT ok for a parent to do this to their children. Don't keep quiet about this, tell the school councilors and tell them every detail you can remember if/when they ask.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
