Don't cry out before you're hurt.

The proverb advises against expressing distress over a setback that has not happened. A feared injury is not yet an actual one.

It also calls for restraint when worry runs ahead of events. Wait to see what happens before responding as though harm is certain.

Use it when someone complains about a possible disappointment or mishap before it occurs. It urges patience, not silence about harm that has already happened.
