i have once lived in a bare box alone for like 10 years with only a computer and myself to keep company. basically solitary confinement almost. one time i was really messed up mentally and basically sat in one place for 3 months only moving to get up and poop or eat a nutritional bar. completely in my own head staring at a wall the rest of the time

my living arrangements are still spartan. this shit would be a piece of cake
