Go see a doctor, you might have a heart attack. Moreover, these things happen.
Yeah I mean it could be nothing but I I were you I would either search the internet for people with similar incidences and see what they did or just go and see a doctor to see their opinion.
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.
