You missed that train. The station isn’t closing.

One missed chance gets treated as the closure of a whole category, which is almost never what happened. The service continues. What you actually lost was a specific departure at a specific time, and the panic is about a much larger loss that has not occurred.

After you miss something, separate the two clearly and out loud. Name what is genuinely gone, which is usually small and specific. Then find out when the next one is, in actual terms rather than in the vague dread version. Most of the grief about missed opportunities belongs to trains, not stations.
