I find it fluctuates. Sometimes I feel better not seeing another person for extended periods of time, not even going on the internet. Sometimes I feel the intense urge for companionship. But since I don't have that, I just come here when I feel the need to talk to someone and just post.
I think if a person was truly happy far away from others, they wouldn't visit a community, let alone an online community. So my belief is, everyone here, to some degree, feels at least a bit lonely.
