Well said. While it might have only been the recognition of that feeling, I do think it might reflect a deeper internalization. Though I'm no psychologist; I only have an intuitive, common-sense understanding of the concept of "internalization".

Yes, I can see why some people would have this take. But there are other takes, such as "this person cares and feels things deeply, and as long as they process these emotions, they'll probably come back stronger."
