From what I've seen, there're 3 kind of people that deal with loneliness differently:
1) The average social people, they had grown up in social contexts, more or less, given as granted, so loneliness is more of a pain point.
2) The socially disconnected people by choice or experience, they had grown up like 1) people but after an event or experience they disconnected(implicitly or explicitly) their minds from the social/cultural/(and sometimes identity) contexts that they got used through their lifetime, so loneliness is, more or less, painless, because at this point your deeper existential self is on spot.
3) The socially disconnected people born with clinical syndromes that physically make their minds, really hard or impossible, achieve a basic perception task as connecting/learning from social clues, through a lifetime.

I'm from the 2nd kind.
