FOMO; noun: Anxiety that an exciting or interesting event may be happening elsewhere, i.e., Fear Of Missing Out. I must have this FOMO. For as long as I can remember, and even before that (according to my mother), I have greeted each day early and eagerly, lest I miss out on some event or occurrence that said day may have to offer. I only have morning FOMO, however. Once the clock hits half-past nine in the evening, I’m out. Whatever happens after that can happen without me — no guilt, no FOMO.
