(1/2) hyperfixations are not just "liking something a lot"

you talk about said thing constantly. you stay up losing sleep to think/talk about said thing. you cannot find any other joy or happiness out of said thing. your thoughts are occupied by said thing.

(2/2) they are only used by nd people because this is an experience nd people have. these hyperfixations can go on for months and its hard to communicate with other people if you cant talk about said thing with them.
it is not a term for neurotypicals to use.

they range in severity and some people can have positives in relation to a hyperfixation. but usually speaking, they can alter how you talk to people, what you want to talk about, and your thoughts because said thing is on your mind 24/7
