Try the salvation Army, United Way, etc. Good luck.
I've been there dude. I had a car to stay in do you? Walmart let's you stay the night in their lots. Otherwise you'll have to rely on friends, which can be difficult. So sorry dude.
Damn. Well public pools are a good place to get a shower. Now that it isn't the weekend hit up a shelter? I dunno because I never figured it all out. Sorry :(
Google homeless shelters in your area. I hope things turn around for you.
