Post-Audition Distress Syndrome. It ALWAYS happens. Ever since I started doing theatre in sixth-grade, it's plagued my thespian life. And now it's struck again with the fandub! Please tell me I'm not the only one with this problem? D:
Awwwww! Try not to think about it? I know it's probably easier said than done. If you can't get your mind off of it, you could do some acting research related to it. Like look up some voice over tips, watch some VO videos, etc. At least it'll help you learn about voice overs and take your mind off of the audition slightly. Just be happy and proud that you did audition at least. ^-^ I'm trying not to think so much about it myself. I'm really happy that I tried out though. :) [Edit] I should have said this before.... xP If you don't get picked, at least you tried your best and you can always try for the next one. Or even try one of the voice over productions that other members have. That's what I'm doing.
It's completely natural, I occasionally get that too (and I've been acting for over six years now xP). It's more common for me to be totally drained of energy afterwards though, especially if I had to dance...
I wish I do theater. Anyways, I have it! when Mike enters in MSN/Skype I'll ask about it. But I'm sure he's already in his way to save the day!
You don't have tech week with fandubs so that's already 100% less stressful than a theater production.
