The Wikipedia has the following information about this codepoint:
Worrying is the mental distress or agitation resulting from anxiety, usually coming from a place of anticipatory fear (terror) or fear coming from a present threat (horror). With more understanding of the situation, worry becomes concern, the recognition of a future outcome that could be troubling, without necessarily having fear in that outcome.
