First a little backstory, just scroll down for short version.

After spending a year as a NEET, doing nothing interesting, useful or social, I have now gone back to finish high school. And I can't stand it. It's not that I'm stupid or anything (well, maybe a little), but I've never been able to stand it. That's not so dangerous, as I have no ambitions, but I figure being educated will be a little less boring. So I have a tiny desire to get through graduation at very least, but not enough to get me motivated. What's my solution to all this? Well, first I'll drop out, and then I'll study myself and take all the exams independently (I'll also be doing two years worth of study in one year, but that's not the important part). With this solution, I can do everything on my own terms as long as I fulfill my goals. Right now it seems like a good solution, actually, the only acceptable solution, in fact, I can't wait to officially announce my decision. But there's an uncertainty, a part of me telling me that my sense of reason should conflict with it. There are two problems about the solution: I'll need self-discipline, and I'll no longer belong to any social group. Only I can know if I have the self-discipline, so it's the social part I'll be asking about.

I decided to mention my thoughts to my teacher, who obviously opposed the idea. He says that the social interaction you get through school is absolutely necessary. I might mention at this point that I have no friends. Didn't have any the year I wasn't going to school, and didn't have any the year I was going to school before that. So in a way, he's right, I have nowhere to go for social interaction once I drop out. But on the other hand, I have survived without friends for quite some time. Sure, I've been a little depressed once in a while, but I'm a man, I can live with that. To be honest, he kinda annoyed me. I don't mind if my sanity is question, but he stated it like it was an undisputed fact that it's not normal for any kind of person to live the life I've usually lived and probably will live again. Sure, most people will be more social than me, but I felt like he was questioning the legitimacy of my very identity. From that experience and other previous experiences I've gotten the impression that this is accepted without any question by everyone in the education field. Therefore I turn to you, who are good to turn to when I'm looking for more free minds who are able to question such things. Am I just denying reality when I think that I can do perfectly fine studying without going to school, or is it possible that the teachers and advisers lack proper respect for my needs?

Short version: I'm thinking of dropping out of school to study and take exams independently, but my teacher tells me that I absolutely need school to socialize and be among people. Is he 100% correct?

Do you have a job? That can take the place of school for this sort of interaction.

However, yes, socializing is a necessary part of life. You may have no friends, but you still know people and people still know you. This could easily grow into friendship.

You are backing yourself into a corner; avoid it. Living without anybody would make life a lot harder, I would suggest avoiding your intended course.

School doesn't last forever, what do you plan on doing afterward? A hermit lifestyle will not benefit you.

Unless there's a medical reason, such as anxiety, I do not suggest this choice.

I wrote a long post in response to this and I guess I forgot to submit it.

Basically, it was:

I think that your teacher is full of shit. Learning social skills is something high school is designed for, yeah, but it's not some all-consuming vortex for hanging out. I wouldn't worry about the social aspect of studying independently as opposed to high schooling though; people who want to be social will do so regardless of whether they attend school or not, and if you weren't doing it in the first place, and aren't interested in changing your ways, then what the fuck are you worried about?

Good luck with your studies, I hope they go well. I don't like going to my high school either.

Not currently, but I might consider getting one, as it's actually much more expensive to study independently (you have to pay to take the exams, you don't get a scholarship and you don't get to borrow the books from the school), but there's also the question if I can motivate myself to both study completely on my own at twice the speed of normal people and work. But I haven't told my parents about it, and if they refuse to cover these expenses, I might be forced to get one.

I don't really have much plans. There's not much I really want to do.

It's not that I have the intention of isolating myself completely from everyone, it's just that there's a risk of it happening, as there's no routine social interaction. On the other side, there's always the risk of me being completely isolated even when being among people.

Thank you for the encouragement.

Go for it, the social aspect is completely overrated. I spent four years of high school on the football team and forcing myself to talk to people, and all it did was make me cynical and bitter.

The only thing you might miss out on is having a good teacher to explain and help you. I had some great teachers this past year(all in my AP classes, if that says anything about the quality of teachers today), and sometimes the only reason I bothered with class was because they were exciting to learn from. Maybe a good tutor would help you out in this regard.

Good luck
