I used to be recluse, then had a social epiphany, temporarily .. so I'm now oddly situated because I remember the need and joy of social bond a bit but I'm back to hyperanxious social mode. Which means I tend to go back to walking alone because it's so lighter.
One anecdote, 10 years ago, I went to a birthday party, a time where I hated social gatherings pretty much. Yet the day after I felt 'replenished' of somethings. As if my internal world couldn't satisfy me fully and even dreaded parties were benefitial.
