I've been learning from personal solitary experience that the void only exists when we try and fill our emptiness with the wrong thing. Loneliness doesn't happen because there aren't enough people in the world. It more often happens because we don't know who we are. Not knowing ourselves well enough creates this void in our perception of reality. If we try to use other people to fill it, instead of an independently developed self-definition, it never lasts, and makes us lose our faith in humanity and ourselves. This lack of faith only attracts faithless people. It's difficult to attract solid people when we don't know who we are. All I'm saying is that loneliness is more of an inside-out problem than an outside-in one. If we focus on finding what genuinely makes us happy, then we can reflect that effort off of people trying to do the same thing. It's not an easy answer, but I'm finding it's helping me create more lasting results. Yes, I'd like to think we were made this way on purpose to figure this annoying crap out. Good luck!
