How do you Take Care of your parents when They dont have insurance and you're poor?

Some americans have parents that have health insurance and stuff.
My parents dont have. and i dont have a great job either. I dont even have insurance.

So what happens if they get some serious illness or injury..
Take out more loans and then i’m in debt forever?( since i already have school loans etc that don’t seem to go down). I’m not the only child but i’m the only one that lives close. the others live in other states
