Truflaphobia – The Fear of Being Interrupted
Nobody else has coined a term for this, so I derived one from Icelandic. (Hey, it sounds smart…hell of a lot better than interruptaphobia.)
One of my current struggles is, quite literally, working on being able to work without fear of being interrupted while doing so.
So there you go, Oxford: Truflaphobia, the fear of being interrupted. Put it in the dictionary and send me a check.
