>>1 Hey, I'm a senior in high school as well, so I can understand that stress. Also, that's super cool that you want to be an author. I would love to be a novelist, but I don't have a lick of literary talent in my body, so I'll leave that to you.
It sounds like you're a great person that is getting stretched thin by life, and I'm sorry for you. But I don't think you'll go insane. You'll be fine, and it'll all work out, and you'll come on the other side stronger for it. So good luck! Also, when you do get to publish your first book, you should let everybody know. I will definitely check it out. If you wanna talk further, even if just rant about how crappy school life can be, my email is valdr.dollars@gmail.com.
