Little-Person-In-The-Back-Of-Your-Head-Syndrome

When there is a little person in the back of your head that keeps making you worry about things. This is not meant to be some sort of mental condition and is instead a concept. A way of personifying your anxieties into a sort of anxiety demon. This is incredibly useful as it allows you to tell said personified anxieties, to fuck off. The acronym of this is LPITBOYHS which fits perfectly as we want all of our anxiety demons to go into a pit, from which they will never return.
