Alexythymia–a term used in psychology and psychiatry. Dictionary.com defines it: “difficulty in experiencing, expressing, and describing emotional responses. … Inability to describe emotions in a verbal manner.”
It means having no words to describe or express feelings.
Or, experiencing feelings and having no verbal expressive methods to convey the feelings.
As to this 2016 US presidential campaign cycle, I am experiencing alexithymia. My feelings are just not something I can find words to explain. I will therefore rely on logic as much as I possibly can, but I admit that this year my vote is entirely based upon gut feelings that I cannot adequately organize into good prose.
It’s nice to know there’s a word for it.
