I'm happy to say that by six o'clock last night all was well. I no longer felt the little blow to my viscera and I was able to put the so-so review behind me.
I talked to several writers, read them the review, and they all said it was basically a non-review and don't forget it's Kirkus. They also said that even after all the time they've been writing (one for about 50 years) they still felt bad when they didn't get a good review.
So then it was over and I could not only enjoy my evening but I was able to write this morning with no review hangover.
I suppose Publisher's Weekly is next. That's an important one. Cross your fingers for me.
