If you want to fix the world, start at home. If playing Fortnite is worth messing up your biological clock, causing you fatigue, anxiety and maybe even depression, perhaps you need to get your priorities straight first.
Secondly, I probably don't disagree all that much on the (lack of) merits of the public school systems. Having said that, you can live a life within that system and not make it actively worse for yourself, no matter who is at fault. That's personal responsibility.
Regardless of our opinions, I think the goal of this entire thread is to discuss the shortcomings of the system and how we can make it better and not just blame the kids for not coping well with it?
The point is that no matter how injust "the system" is, no matter who is to blame for your predicament, there's always a way for you to make your situation worse still.
If you find yourself in a hole, stop digging.
