gosh that sounds really difficult!!! (((((((((silentandscared))))))))))))
Have you called T? Can you sit with the alters and some paper - see if they can give you some insight to what the trigger was? Difficult tho it may be, it is important to know if you can, so that you can circumnavigate it in the future.
"not allowed while driving" - nice try! Doesn't always work the way we want it to. I know we switch a lot while driving (personally) but there are at least 2 who can drive (and argue about each other's driving - lol). Driving is when we have the most noise. Hmmmm maybe we shouldn't be admitting this... lol
anyway... wow I have been losing self today too.
Take good care of yourself - do nice things for you and the system - things that feel safe. Try to journal or draw, see what you can learn.
I am just glad you were all ultimately safe!!!
