I would say find God he will help you through it. Along with alot of therapy and professional help.
They actually did a study on this (though I don't have the link, sorry) where they find out that atheists actually do not suffer from as many mental conditions like the ones you listed as their theist counter parts. If you suffer from mental illness I suggest going to a doctor, YA is not the best place for medical advice.
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.
