@daddieslibra My process is normally just that I sit and think of the plot or even just small bits and pieces of the story I'm planning one by one. Don't rush any of it, trust me, when it comes to writing just take it one day at a time.
And always remember, you can't edit a blank page. Whatever ideas you have for the first chapter, write them down and then decide if you like it or not.
I'm a relatively new writer, I've only been writing for a year now, and that to without any guidance.
Oo Also, The best writers are the ones who love to read. Whenever I feel bummed about getting the writer's block I always either read of watch my favourate pieces of entertainment. That always works.
I hope your fanfiction becomes super successful and I wish u good luck!
