The place where we grow up, and the household/family in which we grow up, are very important influences in human lives. You seem to be clear that England, and your dad's home, feel welcoming and comfortable for you. Yes, your mom might be upset for a while, but it is at least partly a result of choices she made.
Apparently she decided to move to Italy and that feels right for her. You are free to tell your dad you want to live with him, and he and you together can talk with mother and arrange for you to move to England. Part of life is figuring out what is best for ourselves, and then standing up for it and seeing it through.
Not always comfortable in the beginning, but necessary.
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.
