What do you guys call short lived Fixations?

Okay, as your average Neruodivergent teen, I fixate on random shit all the time. Currently, I've been obsessed with Heathers the Musical; last month it was Sanrio. My little obsessions last anywhere from a week to multiple months, I think the longest was an entire school year of me obsessing over Gorillaz. I usually call them Hyperfixations bc the word js seems to fit, but one of my friends told me that I was using the word wrong and that these fixations are js my neurodivergent side showing ig. Most of my friends have now js been calling it me being obsessive(which is true, I'm working on it, but that's for smth else and a different story) Anyway, idk any other neurodivergent or js anybody have a name for this.

idk I was js wondering bc I don't think Google is gonna understand my dyslexic ass trying to piece my strangeness into a sentence. 

PS. GET GRAMMARLY, it's a complete lifesaver for my dyslexic folks, I never see my mistakes in writing so Grammarly points them out for me so I don't sound like a dumbass.

Anyway- Night Night, Sweet Dreams Freaks <3
