Well a lot of your problems sound situational. Like they are related to your present situation. I means soon you'll be on your own, in a city of your choosing, having a bunch more freedom to live how you want and explore as you wish.
Would be a shame to off yourself now, when it all could turn around pretty easily when you are out on your own. I'm guessing it isn't life you hate, it's YOUR life. But you can always get a new one of those.
You just have to add new things or move things around, and keep doing that until you like where you end up. If you say you are only 16 and can't, well better to leave at 16 then end it all. If you are willing to be so final, there really shouldn't be much that is beyond trying first.
Moving to a new city has to be less daunting than death.
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.
