Sleeping on the streets(if you are lucky to find a spot where cops will let you sleep), dealing with assholes who hate all homeless people treating you like shit all the time, not having easy access to a bathroom, not being able to shower or bathe, dealing with homeless people who are batshit insane(like one time, this homeless dude wanted to physically assault me just to prove his strength), dealing with homeless people who are junkies(they are constantly trying to steal your stuff), dealing with the freezing cold, no shelter, no health insurance, no privacy, no entertainment other than books unless you want to become a junkie etc... There is a reason a lot of people commit suicide after losing their job...
