My mom died when I was a teenager. I've never known friends or other family. I don't know what it is about me, but I cannot maintain friendships. I'm finally old enough that I don't have to try anymore b/c no one wants to know you once you're over, say, 31, 32... Unless you're rich and powerful and can benefit them. When I was in college I had profound physical pain from the isolation. It felt like I was having a heart attack. Later, I'd tell people I knew well--not begging or anything, just sharing. Invariable, they'd be totally scared off. It's been about 15 years since I've had a conversation with anyone about anything other than work. Admitting you're lonely today, despite the pandemic of loneliness as published in some of the best worldwide epidemiological journals, is enough to earn you ... social isolation.
I read some articles by scholars on the evolution of human responses to loneliness. They believe people isolate the lonely (and other "mentally ill") to protect themselves, as if from a communicable disease. Other research shows depression acts very much like a communicable disease. We're the "sick" ones the rest are terrified of and so they quarantine us. Indefinitely.
The truth of life seems to be that there's no objective justice. Some have, some have a lot, and some have virtually nothing. Oh well...
