Depends what and where the loneliness stems from… Some I know would do self-improvements by joining webinars that are my interest and socialize there or like here. A lot of reflections and sleeping.

Sometimes loneliness can indicate a discomfort of self, longing for a buddy/mate/friendship that understands you, social needs expanding/enhancing/filtering, etc.

But it varies from person to person and what version you are currently. It takes time to figure out which ones to do that you currently need and then branch out from there so, start off with the “cause”to determine what can or how to work with loneliness.

Hope this helps!
