To be honest, I'm way too old to give a shit.
Social loneliness has never been a problem in my life, despite only connecting to handful of people at any given time. I don't party, I keep my social life to minimum. Hell I hardly visit my family even.
Despite this, I'm not at all anti-social, I can hold conversations with others and enjoy company of few, nor do I feel uncomfortable. Which I find vastly different from other similarly reclusive people's experiences. I can't relate to their sentiments either.
Yeah, complete alienation would still be frightening, but in this day and age, that's not even possible.
The little interaction on internet, while some may argue it's not genuine, is still enough to get some sense of connection to the world, and frankly I can't wait till I can retire in peace.
Hell I'd put my head in a jar Futurama style before I die, if that was an available option.
