If you REALLY need to get outta there, say you're going to the bathroom (maybe say you have indigestion or... a period) and then go. Also you should really talk to someone about the problems in your life so that they can help you. I can feel what you're going through; having to hold back rage and sorrow in class... it's hard, and I wish I'd talked to someone about it and let them help me.
Don't make the same mistake I did, talk to someone about it.
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.
