What advice could you give somebody facing homelessness?

I’m an idiot, I haven’t been able to figure anything out to save my ass from ending up homeless again. The bad thing is the street has changed, there not the same streets as before, I heard this through the hobo grapevine, and I just know it. Shelters are closing, people that used to have a home lost their jobs and are now in the shelters, this totally has changed the atmosphere. I most likely will have to fly to a different part of the country where I hope it will be easier for me. Some cities you can’t be homeless in, most people don’t know that, but not every town is hobo friendly. Getting ran out of town by the police really sucks. There’s got to be something that I can do to avoid this scenario. Any advice is welcomed, I wrote a lot so people can goof on me, in hopes that some insight can be gained. Thank You.
