Hey there,
Take it from a guy who's been single for seventeen years: relationships are overrated.
In all seriousness, though, I know and can sympathize for what you're feeling right now.
The best possible advice is honestly what others have said. I know it's something you've probably heard before, and probably not something you want to hear again, so I wouldn't be saying it if it weren't entirely true, but...
Don't worry about it!!!
Seriously. You
will find someone. That special person is out there waiting. I know it.
