I'm going through your checklist:
[ ]Rarely leaves room/house, if at all
[ ]Does not cook, work or go to school
[ ]Low personal hygiene
[x]Have a way too nice mother
[x]Does not talk much
[x]Have been badly bullied in school at some point
[?]Possibly have some neurological or personality disorder [Never spoken about this with anyone]
[x]Prone to depression and in cases bouts of anger [the latter doesn't apply]
[x]Social anxiety (Be it little or severe)
[x]NO FRIENDS
[?]Non-social activities in room [Not sure what you mean by this and the next part. Sorry, I only speak English as my fourth language]
[?]Refusing to do anything expected by them
[ ]Would probably not eat if not given food (Unless there's microwave food)
[ ]Long hair after a long period of being a hikikomori (If you don't get your mom to cut it or something) [Used to have very long hair, but had to cut it when I was in the army (my country has compulsory military service), and kept it short ever since]
Why am I doing this? Even though I'm nowhere as near to being a hikikomori as you are, I believe I can mostly understand how you feel because I was in an almost similar situation for about a year, and also because even though I'm seemingly better off now, there haven't been any incidents to change my general attitude towards life in general. I live with my parents and get suicidal thoughts daily; I'm studying in a university, doing well in my studies and am getting my M.Sc in the near future, but I haven't made a single friend during my time at the university, let alone had any romantic or sexual experiences.
For me, the main thing that got me out of being an almost-hikikomori was a deep interest in the subject I am studying, but as you can see, it has only made me get out of the house frequently, and not helped any other aspects of being a hikikomori. I also would like to visit a foreign country, but in my case I don't have the money, and the field I am studying is very theoretical and academically-oriented, so there's at most a marginal chance that I'm ever going to get a decently-paying job.
As for your problem of living in a small town, I don't really relate to this... I live in the capital of my country, and I don't recall ever meeting anyone with similar interests and hobbies. Well, it is a small country, and the capital would be considered a very small city if it was located in the United States, but still, living around here certainly isn't stopping other people from having a satisfying life. The whole "life is what you make out of it" attitude that always appears in these discussions applies only to people who have been actively developing their social skills since their early teens I believe. For people like me and you who haven't belonged to any social circles for a long time, it's going to take a complete personality change, and possibly professional training to get to know people to the level where you could consider another person a friend.
