Struggling with basic decisions

I've heard that struggling with decision-making is a trauma thing, but WHY? Is it because we have a hard time trusting our gut now that we've been violated? It's so annoying. My work is ordering lunch and I agonized for like 30 mins between 3 different sandwiches and 2 salads and got so anxious about this decision for no reason. (a little bit tied up in old eating disorder stuff but mostly just over analyzing every ingredient, taste, fullness, name of the item even.) I finally just picked one and now I'm stressed that I picked the wrong sandwich lol. but I get this way about everything. scheduling appointments, choosing activities. etc. such an irrational panic of MAYBE THAT WAS THE WRONG CALL all the time. the funny thing is that I don't even technically have generalized anxiety anymore, according to a couple recent measures. I just get anxiety over random shit.

anyone else? how do you make peace with basic decisions?
