How to stop rehearsing arguments in your head at night

It's 11pm and the argument ended hours ago, but you're still in it. You're rewriting the line you should have said, rewriting the one you did say, and somewhere between the two you've started an entirely new argument in your head, with someone who isn't even awake.
Why your brain won't let the argument end
When a conversation goes badly, your brain files it as unfinished. Not because you're dramatic, but because it treats unresolved conflict as a loose end worth chewing on. In the moment you were managing your face, your voice, your timing, and their reaction all at once. Later, with the room quiet, the brain goes back through the tape and tries to solve it properly, at last, without the pressure.
The problem: it has no one to solve it with. So it runs the scene again, and again, testing new lines. Every rehearsal feels like it's getting somewhere. None of them ever do, because the other person isn't there.
The filing cabinet that never closes
Think about a stack of unopened mail on the kitchen counter. Each time you walk past it, your brain nudges you. You don't have to open the letters, you just have to stop seeing the pile. Most nights, that's all the argument loop is: your brain walking past the pile again and reminding you it's there.
This is why 'just stop thinking about it' doesn't work. The pile is still on the counter. What actually helps is giving the pile a drawer to sit in, so your brain stops checking whether it's still out.
What actually breaks the loop
Rehearsing is not the same as processing. Processing means you learn something you didn't know before. Rehearsing means you feel the same sting on repeat.
One way to tell them apart: if your mental argument is trying to win, it's rehearsal. If it's trying to understand what happened, it's processing. Winning can't be done alone.
So the goal tonight isn't to solve the argument. It's to close the tab, at least until tomorrow, so your body can stand down. Your heart rate, your jaw, your shoulders are all still in that room. They need a signal that the room is empty now.
The 9pm rule
If you catch yourself rehearsing after a certain hour, decide there and then that nothing productive will come of it tonight. Not because the issue doesn't matter, but because your tired brain is a bad negotiator. Whatever you decide at 1am, you'll want to change at 9am.
It's fine to write down one line, 'I want to ask her why she said that', and leave it. That's the drawer. The pile is still there, but the counter is clear. Tomorrow, with sleep, you'll know whether it's worth a conversation or whether it was just an old bruise.
Try this today
Tonight, before bed, open your journal and write this, then close it:
What did I actually want from that argument, underneath wanting to be right?
Writing it down moves the loop out of your head and onto a page, where it stops looping and starts looking like one sentence. The question shifts you from winning to wanting, which is the only part you can act on tomorrow.
Before you put the phone down
Open Sojiwa and start a new entry. Paste the prompt above, pick the mood that fits how you feel right now, and leave it there for the night. If you want, tap the date at the top of the screen and back-date it to when the argument actually happened, so the entry sits where it belongs. You don't have to write more than the one line. The point is the drawer, not the essay.
