I’m not sure if it is limited to only writers (my gut says no), but paranoia about our work seems fairly widespread among the author’s groups I belong to. Comments such as: oh no, I’m not ranking high enough on Amazon, people hate my work! Or: sales have dropped off this week, people must hate my work! Or: I got a negative review, my work is crap! And on and on.
It’s amusing but telling, really. We live and die (hopefully figuratively!) with our books and our current works-in-progress. When doubt creeps in, so does the angst. Not a comfortable situation, but when I see that others who write are in the same boat that I’m occasionally in, it at least gives me a bit of comfort. And we take comfort where we can find it, don’t you think?
