Storms feel permanent from inside them. Check the sky in an hour.

Being inside something bad removes your sense of its edges. There is no weather map when the rain is on your face, so your mind fills the gap by assuming this is simply how it is now. That assumption is a feature of where you are standing, not a fact about the future.

When it is heavy, try to make the next hour smaller rather than solving the whole thing. Get a glass of water, get outside, tell one person how it is going. Then look up later, because conditions change more often than they feel like they will.
