Being alone doesn’t always make you lonely, and loneliness doesn’t always mean you’re alone. The feeling of loneliness derives from feelings of helplessness or hopelessness.

Counterintuitively, some people make you feel lonely. Abusive people, even if close to you, will often make you feel lonely. Apathetic people can also make you feel lonely.

I’m not sure if this will be a revelation to everyone but it was to me.
