I would say it's not just behaviors but isolation causes stress on the body that increases more irrational behaviors and fears.

So that can be crippling when trying to get back to a health state that can handle relationships again. On-ramps to help destress the environment would be helpful too. It's a challenge because we haven't really built many areas where people are welcome to just be, even with 3rd spaces that doesn't those people that are now rewired in their stress state. Some types of maybe community service (clean up, plantings, painting etc) or festivals events might be more helpful here as they can sometimes be lower stress, no required interactions etc. It's a tough thing especially as people have different reasons to isolate though poverty is likely one of the most major ones.
