Is there another SINGLE PERSON in this world?

Am I the last single person alive?. I'm only 22, but everyone I know around my age is in a happy, succesful, long-term relationship. And I HATE IT!. I hate being the only one!. I'm already the only one in a vast number of things, to add "singletondom" to the list.
