They call it a common gesture of courtesy to inform people that your home would offer itself to those fleeing some kind of devastation (oppressive regimes, abuse, earthquakes, etc.). However, most people don’t end up in that kind of humanitarian role. What’s the closest you have come?
Tbh your situation is probably worse than being homeless. So consider how impossible it is to drop further, and use that as an opportunity to do something exceptional. I’d gladly live in my car or in a tent before I’d work two minimum wage jobs. At least then I could go to a library and read all day, develop a skill, or idk, become a monk, a survivalist, a revolutionary, a nomad, or whatever. Much better than being a slave.
