I'm suggesting that she moves so that she won't be homeless. If she were to move, she wouldn't need a dense concentration of microwaves and bathrooms.
She doesn't work, so opportunities to work are irrelevant, though, I wonder why a well educated person with a Masters degree couldn't possibly figure out how to make a few dollars here and there with online or remote work.
And several people in this thread have already explained how she could afford an apartment on her income, so pretending that doing so would be difficult doesn't make any sense.
Finally, I don't see the argument that living in an apartment in the suburbs would be a "worse quality of life" than living in an SUV in a Walmart parking lot and surfing the neighborhood for free microwaves and bathrooms.
