There is an internet meme of the forever alone guy. A person who will never know love, and will live (and die) alone. Sure, it's okay to feel crappy about being single for a while, but it doesn't make sense. It is actually hard to remain alone for the rest of your life.
This comic really describes it very nicely: For all of those who are afraid to remain alone or fear that they will never find a nice mate: Realize that you're the result of generation after generation of genetic winners. You are literally the best evolution had to offer. And you actually worry?
We are the result of millions of years of natural selection on one and one trait alone: Being able to reproduce. Why do you think sex is so nice and why we tend to fall in love with each other so easily?
So don't be afraid. Being a human, you're a sexual creature whose instincts are to bond with a partner. It'll happen. Just make sure you actually come in contact with the opposite sex, so the bond can develop. They have the same instincts, after all.
