Don’t suggest hobbies or human contact. It’s been suggested and it doesn’t work.
I have a job I don’t particularly hate nor like, some coworkers I get along with others are just morons, I go to work, then buy groceries, go home, eat, watch tv, go to bed. Rinse and repeat.
On my free days I do sport and watch pirated netflix. I don’t spend much money on clothing or media and save most of my paycheck. What for? I have no idea. I don’t eat out because I like cooking my own food and restaurants are expensive and the food is bland.
Everything is so expensive nowadays btw…
Most people bore me. I’m like an atheist monk.
I don’t want to kill myself or anybody fwiw. It’s like I don’t give a crap about anything or anyone and don’t see what’s the point of living.
I don’t want to travel because it costs money.
As soon as my cognitive abilities start to fail I’m going to be very easy prey for any online scammer.
Idk if you’d consider it a “hobby” (even though I’d say that has more consumerist connotations), but I’d strongly suggest finding a creative outlet. Personally I believe that there’s no such thing as an “uncreative” person, it’s just that most people never get the opportunity to learn a creatively rewarding skill well (and even when they do, many are left with no time/energy after work). It’s a catch-22. Still, unless you want to keep being a cog in the machine you gotta sacrifice something.
Also, art (in a general sense) is a lot better with human contact, idk what you’re talking about that is “doesn’t work”. You gotta find like-minded people. Sometimes you’re lucky and meet like-minded people by happenstance, sometimes you gotta go out of your way to find them (even if by saying it like that I still feel like I’m underplaying how hard that can be).
A final but perhaps more important suggestion is, learn about something. Instead of binging another tv show every week, mix it up with some educational internet browsing, or books, or perhaps you enjoy videoessays more. Again, an environment where you can meet people is better, but higher education has also turned into a human grinder that spits out ready-made workers for the machine so I can’t sincerely recommend it. But it could still be worth considering (depending on where you are… definitely not worth a 100k debt).
TL:DR find ways of satisfying your inner curiosity and creativity.
