I can't look at a picture of my twin sister without crying?

You need to listen to her! Teenagers go through a lot of things emotionally but never talk about it. It sounds like you need to make sure what your saying to her you need to word more carefully.

As she is getting Offended!. Trust her, let her know you love her and trust her. Sit her down and maybe have a conversation.

I hope things get better but you need to let her know that you are the parent if she hits you then deal with it the right way, your own kid shouldn't hit you! Or anyone. Google ways how you can handle this better.

Or understanding a teenager I know those help a lot!. Goodluck :)).

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.
