AALLRIGHT!!
I got some really cool jobs lined up for you!!
http://www.cracked.com/article_18486_the-5-miserable-vfx-jobs-that-make-movies-possible.html -- compliments of this article!
Roto artist -- It's basically tracing. For a long time. No physical effort, its a computer job, and I doubt there's more than necessary people interaction. Not the highest paying job in the world, but it fits all of the other requirements. Bonus: you made a movie come to life!
Production assistant -- Probably more people-intensive, but they'll be abusing you so no need to like them! You play fetch for them, and do things like be a lamp stand, or get coffee, or whatever they need to make their day nicer. You get the satisfaction of doing tasks you already know how to do all day, no learning involved, and simply interact with the few people you need to during filming. You'd probably get paid a biiit more for this. Not much.
Matchmove artists -- Drawing dots on a computer. for hours on end. Even if you have to learn a new computer skill, it won't be much different from the current one, just different system for doing the same thing. No people again!
Render Wrangler -- Stare. That's it! No, really. That's like all you do.
Bonus: Even if you DO get laid off, there's plenty of other studios you can apply to. The job itself won't be out of fashion, since movies WILL still be made. So there's your job security right there! Or at least as much as anyone can get.
Cons> you may have to move to get these jobs. But any data entry job is the same format with slightly different systems. There are companies whos entire jobs are simply to convert a doctor's offices' medical records into digital data so they don't have folders anymore. And going digital is never going out of style so far as I can tell. not in this lifetime. Computers are where it's at for low stress, low people impact, mindless repetitive work, and all those other perks.
Working as a computer technician of some sort can get you a lot of money too, but it would require more learning and keeping up to date with things. But once you know the basics of something, learning the updated versions aren't so bad.
My BEST option for you: Walmart greeter if you live in America. They're everywhere, walmart that is, and the job isn't people-intensive. Sure, you deal with people, but they generally ignore you and walk by. You blindly say "Hello" to people, give out a few stickers and check the occasional receipt for items outside of baggies. A cashier would work as well! They're low stress and repetitive. Bonus: Benefits of being a walmart employee! You could get health insurance, a retirement package, etc. It's a CAREER, working at walmart. You could stay there 20 years and be set for retirement. Truly you could. If you got ambitious later on in life when you snapped out of it, you could move to different departments, or become a manager or something. So you have job stability (walmart is a huge corporation.. so that's as close as you can get in this world.), career potential, and many of the qualities you were looking for except high pay (though you get automatic pay bonuses as you work there longer, so its sort of like a promotion without doing anything at all!)
It seems you're depressed though.. These are more than ample classic signs of depression, if I can be bold enough to say that without causing offense. To me, you ought to try doing the opposite of the things you're looking for. Try an easy job with people, for example. honestly, I think any job would be a good one to get your feet wet. Even if you can't do physical labor at all, receptionist jobs are easy and monotonous. You DO have to work with people, but it's easy mindless people work. "[Insert greeting here] how can I help you? Oh, he's in a meeting. I'll take a message. Thank you, goodbye." (File papers.) Too easy! I think that'd be a good place to start for you.
And I'd probably use that money for some professional help. Someone in their mid-20s wanting the lifestyle of someone who is retired is nearly unheard of.. I haven't read the responses to the thread, but I wouldn't be surprised if some of them were a bit nasty. It's a foreign concept for a lot of people. You're asking for something hardly realistic in the scheme of things. (They're there, the kind of jobs you describe.. but they aren't good for you. They really, really aren't.) And I think it's because you're in a rut that you may need help getting out of..
It's true. Your mother won't support you forever. (She may.. but let's not chance that.) Getting a job, any job, and using they money for therapy would be a tremendous leap in the right direction. I have friends who are slowly getting on their feet.. life put them behind everyone else, so I know that it can be hard. But I think you're in the right direction by thinking about a job. Keep taking those baby steps and walking forward. One step at a time. Job, and therapy, are essential. You'll get the hang of things as you go.
