I don't really have friends either. I did have, back in high school, but ever since we all went to different colleges, we sort of fell out of touch, not to mention I did not have much in common with any of them. I don't really dwell on it, just occupy my time in things I am interested, like reading and learning, thought now and then my thoughts will wander and muse about it.
The thing is, its not 'friends' but people you interact with as yourself, without having to pretend. Nowadays, the term 'friend' has become too casual. You don't need any of those loose nowadays-styled friends. What I do believe everyone needs is that one person you can fall back to and trust, and also an activity or something you are really passionate about. I believe those two things by themselves can go a really long way, but even without the first, it also greatly depends on whether by your very nature, you are too socially inclined to ever feel at peace by being overly alone.
The people that I'm referring to are the mirrors that will tell you if your life is fucked up. Just make sure that you pick the right "mirror", though.
I disagree with a passion. There is only one person qualified to tell if your life is fucked up, and thats you yourself. Everyone else will inevitably look at it with the lenses of their own preconceptions, interests and ideas.
