You’ve already played out every way it could go wrong. Try imagining the version where it actually works.

The mind rehearses disaster automatically and calls it planning. It will run twelve failure scenarios without being asked and none of the version where things go fine, because success requires no preparation and therefore gets no airtime. The imbalance is not accuracy, it is habit.

Spend equal time on the other branch. Picture it going well in the same detail you gave the disaster: what gets said, what you feel, what happens next. Doing this does not guarantee anything, but it corrects a forecast that has been running one sided.
