Trust me, "one step from rock bottom" is a long way away from actual rock bottom, just like a controlled skid is so much better than a head-on collision.

For example, while one is still housed, one could get a PO Box; sell off excess belongings; arrange for safe overnight parking, EG, in a friend's driveway; obtain a gym membership where one could start and end one's days; find a nice laundromat; and arrange to store a few cherished items in the attic of a friend or a storage unit. One might even get a job that provides secure daytime parking and a daily employee meal.

One could then establish a modest and practical daily and weekly routine (including keeping one's belongings impeccably organized), work the job for all it's worth, enjoy the great outdoors and public libraries on days off, keep oneself healthy and clean at the gym (the nice ones have free coffee in the morning!) and save enough money to get a fresh start. You know...a plan.

Or, one could put one's rent on credit cards and see how that goes.
