I've just hit the post festival blues.  if you've never experienced it, it's the thinking about all the things you did wrong, the strange looks people gave you, the inability to express yourself on occasion, the regret for risks not taken.  It'll pass, but right now I feel really bummed instead of high.  I'm way too self conscious, I think.  Too much me me me.  Right?  

I just have to remember the good stuff, the new friends, the fun and the new knowledge and I'll eventually climb back up.

Of course, I think I also caught a cold on the way home, so that totally doesn't help.
