“Nihilistic are you? […] you have nothing for which to search. [...] I misjudged you. I hope you are just moody, and now in a poor mood”

What you see is not nihilism. While there is Universe, there will always be things to search for. However, they have no influence on the true nature of reality, and moodiness or a particular quality of one's mood has nothing to do with it. And of course, once you find the true nature of reality, there is nothing more to find in that regard. The search ends.
