Call Hosea for the homeless and hungry. Ask them for referrals for your county to get help to get your situation under control. I don't know what county you're in. Fulton, Dekalb, Cobb, Gwinette?

Are you disabled in any way? Apply for SSI disability right away as a backup.
I would do these two things for starters. Organizations have referrals and links to resources that you'll need.
