It might help to be homeschooled whilst you recover from your anxiety. It seems that deliberate exposure to things that trigger it isn't helping, so maybe you need a break from that situation. But you need to know: will you succeed, if you're homeschooled?
Will you get over your anxiety if you're homeschooled? You'll want to limit the amount of time you're homeschooled for. Maybe a couple years.
That said, you're in your first year of high school. I might give it till the end of this academic year at least. I hated the first year of secondary school, and settled in around two years later.
Give it some time.
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.
