I do this. I don't know if it's to stop unhappy thoughts or what, but I end up shouting at myself. Mostly it's actually saying "kill yourself you stupid ****"

I also made a list. My T assumed I was having a bad day and something went wrong at work because of the frequency. I said, "not really, the thing at work went really well. this is just my life."

if you figure out how to stop it, lemme know.
