Loneliness as an emotion is far more significant than is generally looked at. We stereotypically associate it with being recently broken up with, recently abandoned, a trivial neurotypical sentiment whose bearers can’t find something real to be upset about. However, it is much more than missing someone you once had. It is a companion to nearly every major illness such as deppression, anxiety, and trauma, but still appears feeble and weak.
It is an emotion that no one can understand the storm inside your head. It is when no word, song, poem, movie, book, adjective, metaphor, or intangible expression can possibly describe what you feel. It is when some inescapable barrier separates you from other people, and the same barrier prevents you from experiencing the things they do. It is when nothing you do will show people how empty you really are. It is when the more people you surround yourself with, the more isolated you feel.
It is a symptom, and it is a cause. It is not restricted towards those extroverts who are deprived of socializing. it is in fact beyond a need or want to socialize. It is a desire to be understood, and for that understanding to feel genuine and compassionate.
