I used to frequent here for a while up until what I thought was like 4-7 months ago, but I did a google search and my last post has November 28, 2011 (Which is a good indicator of how oblivious you can become to the passage of time). I was without a computer and the internet for most of that time, which was a blessing, because even though I was pretty much drifted away from the novelty of the net and media, though I could have relapsed and become an addict again(am I relapsing now?) Thus I feel obligated to post/update my story, even if it isn't great.
I was NEET for 5.5 years. I applied online to stock shelves at night. And as nervous as I can get (which probably isn't that much), I perform well in actual social interaction. The interview was pretty short, I put that I was self employed and did landscaping, and I've told everyone at work who has asked me that. Being a low paying night job it had little competition for it, so I suggest you start there. It is a small store so there is rarely more then 2 of us there, and there is not much to do. It is not out of the ordinary to have have 3.5 hours worth of breaks in a 7 hour shift, in which we can read stuff/etc, and occasionally mention an interesting factoid from the news. Other then that we usually sit quietly and do our own thing.
I definitely do not make appointments, and I get rides to work, and walk home or phone and get a ride. I guess I could take the bus, but I am not ready for it yet. Interacting with a bus driver... I don't know about that. I also don't consider myself integrated into society, and honestly I don't want to be.
I don't like to be praised in any sort of way, so by applying for a job people would be like "good for you," and this sort of changing of others expectations of me, even positively, is the worst experience to me, so I didn't tell anyone that I had applied for the job, so when they left a message on the answering machine, everybody knew about it before I did, and I didn't like that, but I guess it just means I have a supportive family and I am paranoid. But I guess it feels good to relieve the financial burden off of my family, and I guess even buy some of the things I need/want, but I don't want that much so I am already running out of things to buy. So any excess income I have will go towards buying a remote plot of land and being a hermit/sustenance farmer.
I think something you need is a dream and a plan. My dream is to get away and focus my attention on math and science, in my hermit kingdom. My plan is to bootstrap myself through this bad paying job, and start programming shitty/awesome games to help make me some money. In my 5.5 years of NEETdom I learned a lot about myself after all 'only in solitude do we learn who we truly are.'(<--from a manga), and I learned a lot of other stuff too, like what makes a bad videogame/program, and also how to program, and 3d modeling/animation, how to be frugal, how to tie a blimp knot. You learn a lot of stuff when you are a full-time vagabond of the internet. And I sure all of you have learned a lot too. It is going to hard. But is it going to be harder then the last 5.5 years? I doubt it.
I suggest you start with quitting the internet and other forms of entertainment for a while and just become as stoic and pragmatic as possible. It helps.
