I'm not a social person. I know 3 people of ~700 in my school, and am friends with none of them. I have half a dozen online friends, of which I only talk to two on a weekly basis. After some thinking, I've put it down to 5 reasons: 1. I don't try. During school, for an example. I'm there, I do the schoolwork, then I pass the little time I have left by reading. Or, if there's more than 1 hour, I'd go home for food. 2. I seek perfection. If a person has an annoying trait, has opinions which I'm against (Against, not disagree), is too happy, has too many friends, or isn't serious enough for my taste, I don't even want to befriend them. 3. I find it exceptionally hard to be nice. I don't chit-chat, I won't let things be if I find a flaw in them, and have a general cold/distant/serious disposition, which turns out to be off-putting. 4. Paranoia/Mistrust/Chauvinism. I have some deep-sated belief that girls/women can't stand up for themselves, are easily manipulated, fragile, and so on. When I befriend one, I'm quick to put them in the "younger sister" category- Even though most of the time they're quite older than me, I seek to shelter them from pretty much everything. For my male friends, I'm quick to believe them to be avoiding me if I don't see them often enough. 5. Shyness. As hard as it could be to believe, the few people whom I think might be interesting to know, I will invent reasons not to. And when I run out, I simply don't do anything to try and know them. This applies to "real-life" only, though. And now introducing, the point; is this explained by depression+hormones, or should I be worried? I've no illusions on one day being "Mr. Popular" (or Ms., if I get my way), but I'm also trying not to believe I'll simply die alone after years of loneliness and complete social isolation.
