The prayer may be answered by changing you before changing the situation.

Sometimes what shifts is you rather than the circumstances, and that can feel like the request went unmet. But a changed person meets the same situation differently, which changes what the situation is able to do. The circumstances that were unbearable in one state are workable in another.

When something you have asked for has not moved, ask what has changed in you while you waited. Often more than you noticed. That is worth counting as something, even if it is not the answer you were watching for.
