Relapse of the bad kind of bored.
I get on the internet and talk too much because I'm desperate to express something and desperate to curl up and never say anything again. I feel stretched out and impatient.
Oh well.
Going out on a limb, but I think it might do you good to find and socialize with folks locally. Even if it means trying to chat up a stranger at a coffee shop, and maybe seeing if you can interest them in a game of chess. Or trying to strike up a conversation with someone at the bus stop. Or whatever.
It relates to a cultural and behavioral trend I've been observing in modern society. As we're connecting to one another through increasingly distant means (indirect/achronological electronic communications such twitter feeds and facebook, SMS text messages, this forum, etc), I've found myself with a stronger and more noticeable need to socialize with other people, on a face-to-face basis. Though electronic communications like text messages and message board socialization stuff seems like it would scractch that social itch, the times when I've only had online friends and impersonal social contact (times after I moved, had a sudden social upheaval, or after the post-school friend diaspora, etc.) I've found myself craving deeper and more meaningful social interaction that much harder. There's something in our social mammal brains that needs personal, face-to-face interactions (though even phone calls, voice/video chats with people, etc. can help). Something in our nature isn't satisfied just through this kind of indirect socialization, and we don't feel socially sated by it.
Sometimes that drives us to try to Facebook and Twitter and Tumblr even harder, but it ultimately doesn't help. Even though we're still interacting with people, we can get just as stir-crazy and dysfunctional as when we are truly isolated and alone (think shipwrecked on a deserted island, locked in a dungeon, or holed up in a solitary workshop for months). It's kinda like the social equivalent of Rabbit Starvation; if all you had were vast quantities of lean meat like rabbit, and you were hungry, you could eat and eat, but it wouldn't satisfy you. Just eating lean protein like that won't get you all the things you need to survive, and even though your stomach is full, that kind of diet will lead to malnutrition, illness, and even death.
I don't think we all have to stop Facebooking and Texting and Google-Plussing (...is that a verb now?), but if our lives are relatively solitary ones, we need to be aware of it, and be sure to get our direct socialization time to stay happy and well-rounded.
