How do ppl cope in a dead-end job?

Hello! Just want to know how ppl who are unable to find new jobs, cope with a dead-end job? As my brain is getting rusty ar saturated, uninterested and tired even tho it's dead-end.

There's workload but is so boring, un-useful and dead-end. I felt like I'm a bit burnt out.

Context-im taking part-time masters, but my brain feels saturated to study after a whole day of boring work.
