Fear writes the worst-case script. Life usually goes with something in the middle.

Anxiety is a very committed screenwriter with no interest in probability. It produces the most vivid available version of what could happen, which your body then responds to as though it were a forecast. What tends to actually occur is a muddle: partly awkward, partly fine, over quicker than expected. The middle outcome never gets rehearsed because it is not dramatic enough to imagine.

Write the worst case down, then write the boring likely case underneath it. Keep both until the thing has happened and see which was closer. Over a few months that becomes real evidence you can use against your own forecasting.
