Seconding joining a club. Something unrelated to games, anime or nerd culture in general. I joined the caving society at my university and ended up meeting a Japanese gamer-girl who knew far more about otaku stuff than I did. I stopped caving after three months, but the girl and I have been together for 18 months and counting \o/.

And even if you don't meet any girls you'll at least make some friends, and with friends you'll have an opportunity to go places and meet new people. And if you talk to enough vacuous trollops at parties, you'll eventually find someone you can get along with.

Also, listen to your parents. Don't whine about your life, fix it.
