Congratulations! That's awesome!
Just remember not to be too hard on yourself if you watch the DVD - first performances are always painful to watch (I remember mine was agonising!), and keep that post-performance-glow happening!
And next time, bring a friend to take photos.
maybe you could put the video on but hide under a cover. listen to it for a bit. then replay it and occasionally peek over the top of your blanket. view a tiny slither at a time. and maybe eventually you will be able to view it all.
its the strangest thing that a lot of us feel like this. i wonder what its all about.
