I'm going to say that you should contact your aunt and ask her first. & if your honest with her things can go better. For your mom, I would say that you again need to be straight up and say why you're leaving.
Your going to have family problems your whole life with you mom and brother if you move out. It's risky, but for the sake of your mental and physical health you need to do what's best. Honesty is tough, but it's better to say it then have it forced out.
If your mom gets mad, stay calm! The best thing you can do is not provoke a fight! Don't feed the fire that's wanting to start.
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.
