Assalam alaikum wa rahmatullahi wa barakatuh, Yeah it is, but it's not haram to pray to be a m4tyr: "Oh Allah (swt) allow me to be a m4tyr of your choosing." Whoever sincerely makes this dua after every prayer, will either die a m4tyr or be a m4tyr even if he dies in his sleep as the prophet (s.a. W) said.
In regards to your suicidal thoughts (I think you posted about this before and I warned you it is an unforgivable sin). You need to ask Allah (swt) to increase and renew your faith after EVERY prayer. To increase you in patience, reduce you in anxiety and depression, and also take away these suicidal thoughts from you.
Recite surat al falaq and surat al nas in prayers for protection from evil and Shaytan (who is evil) alike. Think about how many sins you are losing and how many good deeds you are gaining from your struggle. Also I highly recommend you see a therapist and get your head cleared and take some depression/anxiety medication as it seems you are in a bad mental state at the moment.
Stay blessed.
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.
