Well, it sounds like you have pretty good coping mechanisms. And your getting help, and you get to move out. The anger will leave when you keep working things out and living your own life.
Whether you forgive your parents or not is up to you, and it might happen, just long in the future. But once you move out, make sure you cut them out of your life or give them limits so this doesn't continue after you leave home.
You should have called the CPS. Now you are an adult, so leave whenever you want. Your parents are not your parents if they treat you like that.
That's definitely not loving. Another thing, it is not too late to have them thrown in jail.
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.
