I'm as quirky as my kids, I'm afraid

So, for months I've been thinking about going to the DAN! Conference in Long Beach, on biomedical treatments for autism. It's next weekend. I haven't registered, haven't made plane or hotel reservations, havent done anything to make it happen. I'm not sure why (not). Part of me is afraid to be overwhelmed by the sheer quantity of information. Part of me is afraid to be overwhelmed by all the other parents who know more, do more, have more success with their children, ..... But I know it will be really good information, I know I'll be motivated to do more, prepared to do more. What am I waiting for?
