Tell them, if their having a "bad" life, well life is hard and everyone has those opticles and hard times in life where you really have to be strong and overcome those opticles. Their is no such thing as a perfect life, just keep your faith in God and God will help you overcome your problems. The more your close to God, the more he 's close to you, so the more you pray and ask for help from God the more your troubles will be less.
And thank God, thank God that your not as bad as some other peoplearound the world, like those who die from starvation or those who have no family or freinds what so ever, or those who don't have a roof apon their heads to protect them from the rain, cold whether or beaming hot sun, thank God that you have way more than some people can only imagine to have and would never acully have. Love yourself, your life, your friends and family and most importantly God, because if you don't love God or believe in him then your life would never get any better, he is who created you and evey single thing around you and he is who could take that away very easily. So, before anything be close to God and he will be close to you.
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.
