Discussion seemingly endless burnout

[suudo]

I am not in a really bad space in life anymore. I pay my rent at least mostly on time, live fully by myself, learned to cook. I am lonely, but I've been deeply lonely in like half my relationships as well, that's something pretty bog standard. I get irritated that I can't seem to keep friends around for very long, that I'm not exactly someone people take a ton of interest talking to, and I get ghosted pretty often but that's about the extent of my problems in life. I'm about as stable as it gets, I've been living alone for years, and living with just a significant other for a few years before that. I have my fair share of bad history, shit that haunts me to this day but that's... more of a permanent fixture. It's been there long before this burnout kicked in. For all intents and purposes, I should be... if not happy with my life, then at least able to accept I've made it to a place where I'm stable.
I can't shake a desire to disappear though. Either death, or just moving into the mountains and never returning. I am tired of trying, tired of waking up, tired of putting in the effort to care about people, to show a vested interest in their life and have nothing returned, tired of working, tired of going nowhere in a dead end career, tired of putting effort into it when I can survive where I am now anyway, tired of being irritable, tired of feeling lonely, just deeply tired. I seem to have this effective burnout of life, people, time, everything in general and I don't know what to do about it. Normally, when I deal with burnout I take a break and focus on something else until what I was burnt out on can feel fresh again, or I can look at it from a new perspective. The burnout seems to be pervading just about every aspect of my waking days at this point and I'm not entirely sure what to do about it. How would someone go about handling burnout when you feel burned out of everything?
