First off, you might want to do a Discover Scuba, as everyone has said . . . but I'd ask first if you have done any swimming and snorkeling? I'm pretty sure there are places you can do those things in Southern California, and find out if you like the water, and if what's in it appeals to you. Once you have snorkeling down (can clear a snorkel, and clear a mask) you've gotten through a couple of the biggest anxiety-producing issues for new divers.
Second, if you tend toward being anxious, don't sign up for a cheap, big class anywhere. Such classes almost never have the time to slow down for a student who needs to process things in a more leisurely fashion. If you want to be successful, pay more and go for a small class or a private one.
Third, when you say you don't drive, do you mean you don't know how or have a license, or that you don't have a car? I know there have been some people up here in the Seattle area who live without cars, but rent a FlexCar when they want to go diving. I don't know how hauling gear on public transportation would work, but it would also make keeping a schedule challenging, I think.
Lastly, you don't need a buddy when you start. You MAKE buddies in your classes, and by posting on places like ScubaBoard or other, more local boards. I have a significant amount of social anxiety disorder, but diving has brought me a whole slew of new friends (and helped with my anxiety issues about strangers, too!)
If it really is something that appeals to you, I'm sure you can get advice in your local subforum about good and patient local instructors. But I'll reiterate: If you are someone who is unlikely to breeze through, spend time on a snorkel first, and don't try to get through on the cheapest class you can find.
