My advice to you is to just scribble out a paragraph or two of fic. Doesn't have to be every day, either. Nothing structured, just putting down something to make yourself feel better. ☺️

You're absolutely right that even just a quick paragraph, just to get some words out, is something! When I had more time in my life planning would fairly quickly lead to writing, but lately with so much less time I can get stuck in planning forever, sadly...
