I'll second the notion that you DO keep asking and that's ok. But, make sure you're also working on processing the answers in your own head too, because that's where they have to live, ultimately. Also be sure you're not doing the thing where a person keeps asking the question until they get an answer they like. (Not saying you are, just that it happens.) And, last but not least, the answer to some questions is "I just plain don't get this, at least not yet."
But, to try to answer the question. It's really 2 questions, in my mind, because you're talking about 2 different points in time. In the evening (or any other time) if I'm talking to someone like "everything is ok" it very well might mean that everything is ok. It also might mean that the "not ok" stuff is within my capacity to deal with it, so I am. (Because in MY version of reality, my problems are my problems and I'm the one who should deal with them, They aren't stuff that I want to burden anyone else with.) It also might mean that I haven't actually noticed that something's looming on the horizon as an issue, so I THINK everything is fine and will continue to act accordingly, until something blows up in my face. (Or, it begins to affect my behavior, even though I have no idea that anything's bothering me, much less what it is.).
The next morning? Maybe a really bad night's sleep intervened. I might be tired. I might be still fighting the saber toothed tigers from my dreams. I might have had the time to stop and THINK about what I said the night before and be busy berating myself for having said it (for a variety of reasons).
I hope you can find the answers you're looking for!
