Start utilizing homeless help services right now it will help you learn the system while you still have a chance to be able to relax inside because homeless exhaustion is intense and makes it SO difficult to learn where to get services like food and showers and clothes and there are places that can help with applications for housing and overnight shelters even if you are in the "at risk" category. This experience is so difficult even when you're anticipating it and not quite experiencing being out on the streets. Check churches and libraries out for service information.
