Being alone isn't necessarily the worst thing one can do. Hell, I've been pretty steadily single for something like ten years. I'm not going to lie and say it's never lonely (because that's clearly bull****), but the bouts of loneliness do pass, and in the end I think I've gained a better understanding of myself than most people do. And that can only help in future relationships! Because I also believe that the better you understand yourself, your needs and the things that make you you, the better you understand others, their needs and the things that make them unique.
So, I guess this is kind of a 'keep the faith' post.
