i finally asked a therapist why my brain is so obsessed with keeping me awake at 2 a.m. replaying random arguments and awkward moments from years ago.
i expected some version of:
“you’re overthinking.”
instead she said something that stuck with me.
she said,
“your brain isn’t replaying it to punish you. it’s trying to learn from it.”
she explained that when something catches you off guard… a betrayal, an argument, a humiliation, whatever… your brain treats it like a security failure.
it keeps revisiting the memory because it’s trying to figure out what it missed.
what was the warning sign?
what should i have seen?
how do i make sure that never happens again?
suddenly those 2 a.m. thought spirals made a lot more sense.
my brain wasn’t trying to torture me.
it was trying to protect me.
the problem is that after a certain point, you stop learning anything new.
you’re just replaying the same footage over and over.
the therapist told me that when that happens, it helps to write it down.
what happened.
what you learned from it.
and what you’d do differently next time.
because once your brain believes the lesson has been saved somewhere, it stops feeling responsible for keeping the memory on repeat.
i don’t know if that’s true for everyone.
but it was the first explanation that made me feel a little less crazy about why certain memories refuse to leave me alone.
