Sounds like there is not a bullying or something problem so I will skip that one for now.
Are you already in business or reasonably sure you are going into something good? Like during the web bubble if you could do the deed (and the basic scripting and such seen then was not the sort of thing that took time to learn) and possibly be paid if not truly silly money then enough to finance a bit more (millions is certainly nice but a serious chunk of change you can stick into a savings account at 18 or so does get that sweet compound interest) then that would absolutely be a thing to consider. It is a risky thing and I would say you should always have a pot such that you can go back and finish it -- while ability counts for a lot, in fact near everything for me, there are still enough places in the world that want a piece of paper. If you can get enough that if it does not pan out you can fund yourself and the course to say you did high school or whatever.
Don't be in a hurry to run LAN cable and swap hard drives. You might have done a few such things and while the money is likely better than a paper round/working in a shop that your peers find themselves doing it is not the sort of thing to jump into like this and if you are good enough you can do that during evenings and weekends. Beyond that IT is changing massively right now -- I can fix laptops but why anybody wants to pay me for 2 hours to do it when not much more money will buy a whole new machine (or a refurb one) I do not know.
I can install websites and still do but it is mostly grunt work, getting the client to produce some stuff for it (install CMS... 2 minutes, change colours to company colours... maybe 5 more minutes if I have to do a gradient, getting client to cough up photos, text, opening hours, menus, product list... an agonising ordeal even on a good day) and knowing enough to debug a website only really saves me a bit of time. These days I don't even have to transfer data that much as loads keep it on USB drives and online, and web browsers have sign in and share history between machines and bookmark backups.
I can make servers even. Amazon allow me to spin a virtual server up and down as much as I need for not a lot at all, and have prebaked ones that anybody can use without so much as knowing what BIND is, never mind how to actually work it. It is also perfectly professional apparently to send an email from an @gmail (and of course google will host your email on a big boy email setup comparable to exchange in many ways for...

Going further while there are many button pushers in the world and the "the kids what grew up with technology" thing is something of a myth there are still enough people with such skills in a lot of companies, or at least enough with

I could repeat this for most of the bread and butter of the IT world too. There is still just enough out that which can give you a taste of something nice, especially if you are a high school type and looking at your friends, but it is not a good long term plan.
If you are sitting on big boy skills (serious virtualisation, some kind of really hot development, electronics repair worth speaking of) or your business is really taking off and the time you have to spend in school is holding it back then elaborate and let us talk more.
