Yeah, your opening post sounds completely emo. Sorry, bud, but it's the truth. Although I'm sure you don't mind me saying that.
It just seems like you're going through that phase. Most of us go through the same thing. It will pass. And if it doesn't (Or you're...older than you seem), here's something else, then.
I get what you're saying. I suppose I'm a bit of a misanthrope myself (Not saying you are...directly). I've made tons of 'friends' at school, work, randomly, and so on and none of them proved to be what I was looking for. I wanted what others had: A loyal, true friend who accepted me for who I was and could put up with me no matter what, i.e, if I'm in a bad mood and I tell my friend to fuck off, he's not gonna be offended forever, but he'll understand. Something like what you see on TV. And I never found said people. Most people were too different or wanted something out of me that I just didn't want to give because it didn't feel natural. So I withdrew myself.
And hey, I'm happy by myself. But eventually, I found a couple of people who were nice to me and seemed to like me for who I was, god knows why. So out of all the people I've met in my entire life, I can honestly say I have like less than 5 people I consider good friends. Not awesome, not best, but good friends. Friends I hang out with every now and then and it's fun and then it ends. That's all I need.
Yeah, eventually, we'll all move out and we might stop talking to each other but hey, we had a good run. Like someone said, everything is temporary. Video games make you happy only for a while. Food too. Music, TV, other activities, even this thread might only give you guidance for a while. So if you stop and analyze everything like this, guess what? You're gonna be so miserable. If that's what you're into, go for it. If not, then, and I say this in a respectful way, suck it up and move on.
Almost all of us here have gone through the pain of losing someone for whatever reason; friend, family, possessions, whatever. It hurts, yes. But we're all here. We're stronger now than yesterday. And hey, if you think you don't fit in with anyone else, well, that's okay, I guess. Don't force it. Maybe you'll find a good friend someday or maybe not. You just gotta be comfortable with that idea.
It appears to me you're just afraid of getting hurt again and boy, I cannot begin to tell you how many people go through that everyday. But...sorry, buddy, pain is a part of life. You can either learn to suck it up and carry on with life following your own rules whatever they may be or you can just sit and cry about how lame life is. Your choice.
And believe me, feeling some sort of pain is better than feeling nothing at all. Come on, it's been sung by almost everyone now. This is knowledge that you learn when you go through the emo phase. You should know this.
