I'll add my 'alfpenny's worth.....Sqad, naomi, why does it matter and what's this really got to do with 'overall doom and gloom in AB'? In short, it doesn't.
From Dave's perspective, he felt a little down, (not depressed), about a significant day in his life, a day that many here have gone through and felt the same way as Dave does/did - so in that alone, there's nothing wrong in 'vocalising' it and, indeed, the very expression of the emotions involved in this may help others approaching a day that can feel gloomy for some of them in that this is a more general 'experience' than may first be thought.
