Is there such a thing as "submitter's remorse" when one sends out a manuscript? Heck, I haven't even sent it out for publication, just for an initial read by some friends of mine and now I'm thinking "Ack! What was I thinking? This is a self-indulgent mess!"
Then again, I'm grappling with a slight case of depression, so that may just be the serotonin deprivation talking. I suppose I'll find out whenever I hear back from the folks I sent it to.
