Have you tried remote work sites, or something like upwork? Is there an unemployment office near you? It might even be your location, per my understanding jobs are more abundant in urban or close-to-urban areas, but require having a car or housing in that area. What if you secured a job first via an unemployment office (don't mention activism stuff, or political stuff), and then apply for something like housing for low-income folk? Just some suggestions.
I suggest doing odd jobs for the couple helping you, as it might at least help them understand you're not exploiting them. Good luck.
Edit: not sure if the tone of my message is coming out right, but its not meant to be judgmental or challenging you :)
