What is the fear of having regrets called? What is the clinical name of fear of regrets? I'm thinking of something like arachnophobia or something ending with the prefix &quot;-phobia&quot;
could it be something like apóleiafovía? (the literal greek translation of fear of loss)
Although not a clinical diagnosis, in research on social media the term &quot;Fear of Missing Out&quot; (FoMo) is often used (Przybylski et al., 2013):

Defined as a pervasive apprehension that others might be having rewarding experiences from which one is absent, FoMO is characterized by the desire to stay continually connected with what others are doing.

This sounds related, but perhaps more specific in that it focuses specifically on regret of not having experienced a rewarding experience online.
