SSI, if that is what you're looking into, has a process for people who don't have verifying documents. Just keep appealing and you should be able to get to someone who can "assess" you. And, when you do applications and interviews, they don't wanna know how you usually do, they wanna know how you are on your WORST DAYS. SSI is also for people who both cannot work at all, or cannot work to their full potential due to disability.
