You concentrate on things that matter in life, like school or your career etc. You get a makeover, hang out with friends.. but the important thing to do is to ALWAYS keep your mind busy enough so that your emotions don't have time to sneak up on you. In time you won't feel as broken up about it as you had in the beginning.
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.
