Hi Emily1987,
I seem to recall something about 'unfriending' inactive ones, but it was probably just a one line comment that might have not been actually written in the talk outline. Somethings COs and other righteous ones tend to ad-lib their parts a llttle. Its also not that unreasonable though, for it to get around the congregation that a person has decided to cut off a certain person from social media, and others end up copying it too.
As hard as it is to adjust, you should start thinking about joining a club. An outdoor one, like a sports based one or something. We all need company, and you'd be surprised how friendly and genuine some 'worldy' people can be.
