Writing issues

It's odd, but ever since I published my book, I've had trouble writing. I hate that.

I really don't know why. I have managed to revise and expand the original world-building story which was only 10,000 word. Got to a stopping place at 47000 words, just short of a novel. I want to go further, to link this story to the sequel I have ideas for, but it just isn't coming.


I've considered going back to fanfiction, but that is not working real well either.

I guess I need to just keep trying, but it's frustrating.
