I always thought it was about a family with a child (of any age, from small to young adult) who was sick, and no one could figure out what it was, so the mom was crying because she was worried and the dad had to pick up a lot of hours at work to pay for medical expenses. And the kid is worried that it's all in their head because no one can find what's wrong, but they still feel bad and worry that they're going to die before they can be cured.
I think it's about being chronically sick and feeling guilty because everyone is worried and has to pay for it.
