Oh to be young and full of crazy ideas again.
Here's the thing, young fawn... If it's complete and total isolation you're looking for (because let's face it, we all know I didn't read anything other than the OP because that's just what I do most of the time. I'm sorry), you aren't going to get it no matter how hard you try. You will have to interact with someone face-to-face at some point.
I myself am a pretty socially isolated person. It isn't necessarily by choice, it's just that I've gone through over 20 years of constantly being very hurt, disappointed, and let down by people in general- including my own family. So I'm incredibly weary of anyone new coming into my life. I'm very protective of myself and my feelings and my kindness now. Because if I choose to let someone in, it's usually not just an "Oh this is an acquaintance I sometimes have lunch with" type of thing. It's more of a "I will go out of my way to be there for you if/when you need me" thing. And 9/10 it never ends well for me and I'm left emotionally drained and depressed. And once someone screws me over/hurts me, I'm done. I cut them out and I don't look back.
I have my fiance. And I'm lucky to have him, and I'm very glad I do, but that's pretty much it. I have a very small handful of friends that I love dearly even though I rarely get to see them because of distance, but I'm okay with that. I know they're there and they know I'm here and we talk fairly often. My fiance is pretty much my only form of physical, face-to-face social interaction on a daily basis. And that's also okay.
ANYWAY.
You're only 17, mate. You're hitting that age where you think you have it all figured out and you know it all and you know exactly what you want in life, but trust me when I say you don't. And you won't until much much later on. I'm talking like 10+ years. I'm 30 and while I -do- kind of have my major life stuff figured out for the most part, things are still iffy for me. I haven't been in 1 home for more than a year in 11 years. Where I live now, this is the very first time I've -ever- renewed a lease on an apartment as an adult.
Don't go all gung ho on this idea. Go to college, get a degree, do all that stuff and live your life now. You're selling yourself short by automatically assuming that being entirely isolated is what you truly want. You don't want to jump into something like that. I can almost guarantee you that in 6 months or a year down the road, you'll be kicking yourself and regretting your situation and wishing you'd done something different.
