@guerrillarain Writing is hard for me, too. It's gotten easier the longer I've struggled with beginning this new habit. Related for me: doodling. I used to draw a ton of doodles when I had a moment, and it let my creativity flow and whimsically. I was struggling with the same for writing, but I conceived the closest word to express the same was "scribbling."
Try "scribbling" a little prose until you can be tied to a piece, maybe?
Good luck.
