Docs are taught that the normal time period for mourning the loss of a loved one is six months to a year after the death. So it may be natural to experience depressive symptoms during that time. But I want to make it clear that you should never feel pressure to shake the pain after a certain time period.
Illusions are also a part of normal grief. An illusion is a misperception of actual external stimuli. Delusions or hallucinations are never normal.
The key is getting to the point where you can decide whether the discomfort is enough to carry on with other aspects of your life. That takes many people one to six months, but it takes others longer. Don't hesitate to seek help.
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.
