Meh. I went by myself my first year, and it was absolutely amazing. Don't be afraid. Just buy the ticket, and take the ride. You'll find friends in about ten seconds flat, and that's a guarantee. Park your car, walk up to your neighbor, say, "Hey, my name is ____ and I was wondering if there was space to camp here?" and watch the instant lifetime friendship unfold.
Read the survival guide, read the eplaya threads that interest you, and ignore videos like "Oh the places you'll go" because Burning Man is entirely what you make of it. If you bring a tent with steel stakes and an EZ-up and expect to get handed free drugs and participate in orgies under the sunset at loud rave parties, you're gonna have a bad time. If you prepare adequately for the sometimes harsh and nasty weather, if you get in the mindset of participating and contributing, and if you are prepared to have both terrible experiences and amazing moments, you're going to have a great time.
