One other addendum I wanted to make about the isolating effect of exile is that being exiled does not 'doom' you to having no more friends forever but puts you in a socially hibernated state that can slowly atrophy you. It's a matter of time more than anything else.
If one of the few places you are at left turns on you youre going to take distance and be even more cautious about who you associate with. While there is no surplus of communities there will eventually be an opening, the issue is whether you are in any state to join it by then and if you even want to.
Even if you aren't actively socially atrophying, you are bound to get more weird and quirky. For instance, the fact that I do these disaffected antisocial pontifications is a result of not being in active social spaces irl for over 2 years now. At this stage it may be nearly impossible to unlearn.
