Unanswered prayer can feel like silence. It might just be a longer conversation than you planned.

Nothing coming back is not the same as nobody being there. You asked, the situation did not change, and the natural conclusion is that nobody is listening. There is another possibility, which is that this is a longer exchange than the one you had budgeted for and you are partway through it. Neither reading can be proved from where you are standing, which is awkward and also honest.

Keep asking for the same thing this week rather than switching to something easier to grant. Write the date on it. Leave the question open without closing it against yourself.
