I'm really really sorry you feel that way. You are not imcompetent or pathetic. That is simply what this crappy school system has taught you to think.
But here's the deal, suicide is a permanent solution to a temporary problem, things will get better. School is almost over, power through the last few weeks of the semester, use the break to help you get things put back together. Talk to your teachers about what you can do to raise your grades.
Take a little time to just breathe. Yes, your life isn't great right now but I can honestly promise you it will get better. Why kill yourself before you have to die?
You'll die before you know it so why not have a little fun before that. Try to put things in perspective, you've only experienced 17 years of this world, don't you want to find out what the next 17 years can be like? They will be so different and so new.
And someday you are going to look back on this time and be so glad you chose to stay and work through it. You are strong enough to get through it you can do it. I know I don't personally know you, but I really believe in you and you can get through this.
If you ever need to talk about anything, you can talk to me.
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.
