You WROTE A NOVEL!
And it’s good. :-) And people read it because they like visiting the world you created and spending time with the characters who once only lived in your head.
They’re in the world now, breathing and being, in the hearts and minds of everybody who loves them.
So focus on that. :-)
But, beware. Writing novels is like snorting coke. The high is intense, and sometimes all you want is more.
So guard your superpower carefully, and use it only for good. ;-)
(Superpower? Hells yeah. Only an exceptionally small percentage of writers who start novels every finish them.)
