Hi there.
I've got some autistic traits (according to my pdoc) and my son has asperger's. All I can say is that if you discover you do have an autistic condition, it's not the end of the world. You're the exact same person you were before diagnoses, but you'll have more information about yourself to help you in life.

There are groups for autistic people in most towns, and many autistic people are very succesful in their chosen careers. My son would never have been born if I hadn't fallen in love with his father, who has asperger's syndrome. The fact we split up had as much to do with me as him... it is possible for someone with asperger's or autism to find love and have a relationship.

It might be worth finding out if you're on the spectrum, because if you are then there's help available. And don't give up on the idea of love just because you're "behind" your friends. Folks I know on the spectrum generally start out later, but don't go through as many one night stands and empty relationships as others.

How old are you? There's plenty of time to meet someone, and for it to be the right someone.

Don't get depressed about it, just use it as a tool to understand yourself. That would be my advice.
