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.
There are some decent comments here overall with stuff I bet would help you. But it sounds to me like you have lost the appreciation and rewards from life and the world around you. I would wonder if you have undiagnosed anxiety.
This isn’t going to sound great probably, but the problem isn’t the world around you, it’s just you. The good news, ‘you’ is the only part of this you can fix. The rest, totally outside of your control.
You need to retrain your brain. Slow down to appreciate the smaller things. Even the tiniest things. Read up on the raisin technique. I think raisins are kind of dumb, but apply it to everyday things. Go slow. Examine. Savor. Eat slowly. And with each bite think of the process that got that very thing into your mouth. From growing the ingredients, raising, milking, whatever. The process and storage, maybe inspection, transporting it to the store, you buying it and cooking it. The skill it took to do that and the history of you cooking to get there. It’s an awful lot packed into each bite. Do that with as many bites as you can. Be mindful. Repeat it. You don’t need a different thought every time. Just keep thinking it through. And apply that to more things throughout your day as you’re able to. It’s not an overnight process but it’s much faster than you might think to regain the value, passion for things. Do this people as well. Forgo the NPC thoughts, and delve in. How they got to be who they are. Ask questions over time and build a mental roadmap.
That’s pretty much it. I could have easily written your post word for word a decade ago. With therapy and general learning, fighting anhedonia was a process. And still is. But I do appreciate things and I look forward to things. I often look forward the most to me not being me tomorrow but a slightly better version of me.
