This kind of makes me want to read Welcome to the NHK again. I personally feel somewhat close to Neeko, but I guess in the real world being a NEET is not as relaxing as it is portrayed in the manga.
I've spent 3.5 years being a NEET (the only reason it wasn't longer was because I had spent the few years before in university, so I had one of the E's), had problems with depression/anxiety, and it was like trying to dig yourself out of an ever-expanding hole. The problem is you had several problems interacting with each other and it formed a downward spiral that gained momentum every passing day. My mental condition would affect my sleep, which in turn makes serious work almost impossible, which then means no progress and further anxiety and even less sleep at night.
Eventually I found a combination of meds that worked for me after the so-called "med-go-round", when doctors prescribe random combinations of stuff and hope to find one that works (the meds were not random, but the effects were totally random). From there, I gradually started trying to find work again, but then I ran into social anxiety...
It wasn't obvious when I was spending most of my days at home, but not talking to people for a long time will make you... forget how. I had trouble meeting people's eyes when I talked. So after some thought I enrolled myself in school again: I figured I'd kill two birds with one stone, I can reconnect with society and learn to develop software at the same time. That was last year. And here we are at this point in time.
In a bit less than 6 months, hopefully I can find the job I've always wanted, and finally go from one of the E's to the other E. It will have taken 5 years to dig the hole, jump in and dig myself out, but I'm glad I did this instead of throwing myself down the 17th floor a few years back.
So what's my point of writing all this... I guess just to say that some people aren't choosing to be NEET.
Like Neeko, I played video games, read manga, watched TV shows and all that, but I did that because I needed the distraction, not because that's how I wanted to spend my day. I too wanted to go out and be an independent human being. Knowing it's a manga, hopefully Neeko has a better time than I did overcoming her adversity.
