Does anyone else get a plethora of 'potential outcomes' for every action you consider taking?

Like every time I say something to someone on text, my brain immediately starts listing possible replies maybe to prepare for what to say next?

Same, with any other life decision. Like if I do this, then this could happen and therefore this could happen and so on. In pretty much every permutation. And until my brain is done doing all this, I'm just kind of paralyzed waiting for it to finish.

It's almost like it's a standard process I have no control over, and I just have to endure how much processing power it takes.

Could this be why we get so overwhelmed? The more we engage with life, the more permutations of alternate life paths sprawl out in front of us. On the other hand... the more we stick to routine, the less we have to 'predict' and we can relax more?
