As an author some things become difficult. Maybe you have writers block? Do not worry. I'll give some advice that I never got when I started out.

Writers Block
≫ Every single author has gotten writers block, even the greatest. You just stare at the screen but you can't type and that's okay. You can get out of the block easily. My suggestion: Get your mind off of writing. Maybe draw, play a game, have a snack to get your mind off of it. Then, see what you think would work well with the story plot. Some times writer blocks take days to get rid of, and that's fine too. If a break doesn't work, get inspiration. Read other fan fictions or even some of your favorite books.
