weird suggestion but lay down and cuddle yer pillow, (body pillow, throw pillow any pillow or something you can snuggle with), and intensely think. idk man it helps me get motivation for fanfics and xreaders that I know I'm gonna regret writing, preferably late at night, 12am to 6am. just think, or imagine the characters ya wanna write about kinda doin their thing. if ya think of anything gud then get up and jot down ideas, for yer future self in the morning, or whenever u write.
