When I notice that I’m thinking painful and likely untrue thoughts, I think of it as my brain trying to go to or already in The Bad Place (aka: negative sentiment override, assuming the worst, being pessimistic, running a maladaptive schema, bad programming, telling yourself bad stories, feeding the bad wolf, sending out negative energy, trauma response, being triggered, starting to get flooded).
When I am in the Bad Place I can still function, but only just barely. Others see it as me being rude, inconsiderate, stupid, ridiculous, mean, unkind, self-centered, selfish, stubborn, bossy, pedantic. I’m trying to get into the habit of wearing noise cancelling headphones so I can tune out other people until I’m functional again. So far just keeping my mouth shut as much as possible if I’m in the bad place is working ok.
Headphones would help, I’d need active noise cancelling headphones: Bluetooth, comfortable.
