I just asked this question: [What is a word or expression to describe anxiety about the passing of time?](https://english.stackexchange.com/questions/40849/whats-a-word-expression-to-describe-a-feeling-of-anxiety-about-the-passing-of-ti)

It's my first question on English SE, though I am a long-time StackOverflow user, so I understand how the system works in general.

The problem is, I don't know how to tag my question on English SE. I found the tag `single-word-requests`, which seems appropriate for the question I asked, but on the other hand, I expect that there may be an expression that is more appropriate than a single word.

Please suggest the most appropriate tags for my question.
