Could just be a downswing, I've read a small handful of posts recently where people are feeling down about various things and even Eldest was on a downswing recently though he's been smart and is taking the advice I gave him and thus has learned to find things to help moderate his moods much much quicker than I did.
Setbacks always happen but hopefully the album and the show are progressing generally well :)
