Well, in my case, those small momentous things would have helped delay the process, but ultimately the outcome would have probably been the same, if not for the actions of a certain group of individuals.
But Kappa, you're in a different situation, I understand that. However, look at it this way. Yes, you may (or may not? IDK the situation besides what you're posted here) fail this class that gets you booted from the school. I doubt that, there's gotta be some makeup thing, but we're going with worst case scenario here, so, ok, you get booted. Your mom (and you) says you're not going to the local public school because it's so bad. As far as drug problemss go, EVERY HIGH SCHOOL HAS THEM. I'm in a school of about 150 kids, and I'm constantly astonished by what people in my own class talk about like they're commonplace. That's beside the point, though.
Anyway, if your mom was being honest in saying they'd move before you go to that one school, what about the next one down in the district, or the next district? Don't move, just go there. If none of those wor, and you do in fact move, you say you can't live with the guilt of your own problems causing your family's life to be so transplanted, turned upside down on your behalf. Man, I gotta be honest with you... This has gotta be the stupidest point of view I've ever heard. For one, it would be your parents' choice ultimately, not yours, so you can't blame yourself for making them do anything. In addition, your parents' chief, number 1, ultimate priority is to give you the best of everything they possibly can. They want you to be as best prepared as possible for the rest of your life. How can they do that if you kill yourself?
Also, consider this. Which would be worse for your parents? Moving away on your behalf because they want to (they want what's best for you) or you killing yourself? I'm not a parent myself, but I do know that the worst thing a parent can possibly go through, would be to bury their child. Almost all parents, regardless of how great or crappy of parents they are, if they're given the choice of living miserably on the streets, suffering some horrible disease for the rest of their lives, or giving up a child, they'd choose the former in a heartbeat. This is bred into the instincts of every semi sentient species on the planet. You'd be doing infinitely more damage to your parents if you were to kill yourself than you would if they were to move for you, let me tell you. So quit making reasons why it won't work or why this is the best option and LIVE YOUR LIFE. You're not even an adult yet! These problems won't last forever!
And besides, even if you drop out of highschool, you'll do ok at life.
I hope that gives you a little bit of a different perspective on things.
