hmm, I've had sucky jobs and was lucky to get out - I've now been job-free for 8 years though and it's no picnic, luckily I live with my parents though it's not always so awesome either

so take what I say with a grain of salt. But what would happen if you started to 'slack' and 'play the system' too? For at least some of the time? Call in sick now and then? (it sounds like you've been sick anyway, but did you go to work anyway?)
I'm sorry if this sounds a bit 'unethical', you do need to maintain your sanity though!
All those angry people at a power outtage - can you really actually do anything, or just 'take their anger' - maybe the bosses and others are actually smart to just hide and let people time to 'cool off'??

Also, could you start a 'side hustle' doing what you love - repairing laptops, doing techie things...? after work - even if just volunteering (for an NGO or for neighbours) if you don't need the money - though it sounds you'd like that morgage paid?

Just some thoughts...
