Pressure becomes manageable when you stop adding imagined problems to the real one.

Real difficulties are usually manageable. What makes them overwhelming is the additional set of imagined consequences that the mind assembles alongside them, each of which feels equally present. You end up handling one actual problem and six hypothetical ones simultaneously, and the load becomes impossible for reasons that have nothing to do with the situation.

Write down what has actually happened, then separately write what you are afraid might follow. Deal only with the first list. The second is worth acknowledging and it is not currently your work.
