I'm writing a fanfiction story and I've been having the worst writers block. I see what I want to happen in my head but I can't put it on paper for some reason.
My best advice would be to just write something, even if it's not the thing you are supposed to write or have to write. For instance, look up writing prompts online and try one that interests you. If you're struggling to get through certain parts of a story, write the interesting scenes that you really want to write (I'm doing this right now for my current novel), rather than writing the whole thing in chronological order. After all, you can put the scenes in the order they're supposed to be in later on, when you have them all written. There's a couple of websites too where you can challenge people to write-offs, seeing who can write the most words in a certain amount of time with a specific prompt. A little competition may be the perfect thing to find some motivation!
