I would strongly suggest that you try to apply for disability again. Has enough time passed since the last time you applied that you are able to do so again? (Sorry if that question sounds ignorant, I really don't know anything about the process.)

Check your county's department of jobs and family services website to check and see what social assistance programs are available in your area.

It sounds like you're in an incredibly stressful situation, I really hope things start looking up for you.
