Try to catch yourself thinking it and come up with alternatives. Like guess it’s time to run away and join the circus, or I am going to jump into a river and turn into a trout. Also being very sarcastic about it. Like I dropped a plate of cookies, I should go become a waiter with these skills. Or, I am the best ever at holding stuff. It’s going to take a lot of active effort to both catch yourself every time and also actively change your thought process but you can definitely do it
I guess for me, I made a joke of it? when I caught myself muttering that reaction outloud to myself in frustration, I realized that it was actually kind of funny by nature of what a disproportionate response it was, so then I started saying it flippantly in front of other people too. and eventually joking about it helped the thought itself become less serious
