..hey, I'm from Jersey! lol
But seriously, just be happy with yourself right now. Be positive, be a good person. Don't look for a girlfriend just because they're pretty or popular. If you find someone you really like, be open with her. try to find someone you really connect with. Although, this sounds pretty far out, since no one really finds the perfect girl on the first run through.
And no, you shouldn't have to give up your hobbies. I personally love video games, love FFXI, love anime, love all that good nerdy stuff. Though I'm not like the general population I guess, I'm sure you can find something you have in common with a girl. You shouldn't have to change for her, and she shouldn't have to change for you, but you have to be willing to give up a little of your time to be with her.
Good luck, it'll be hard, but it's worth it, I'm always around to talk if you need it.
