I know exactly how you feel. I had that same feeling writing my book for almost a year before the rest of it finally came to me and I was able to finally tie it together (coincidentally, due to publishing difficulties, I'm posting it chapter by chapter here on Steemit). Sadly, I don't have any good suggestions. I'm having the same trouble trying to come up with content to put up for a couple of projects I'd had previous to my hiatus.

If I find something that works, I'll let you know lol
