Why do you not care about not caring about people who don't care about you? The opposite question comes to mind: Why should you care?

You have your life and as much as we might "like" to care about the starving in _______, we don't have that much energy/focus to be able to do that. It doesn't sound like this person was contributing anything at all to your life? And, it IS all about our own lives; she was sort of correct about saying it was about her but had her reason wrong, it seems to me, her life is all about her but your life is about you and deciding that her dying should be more important than your living/dying doesn't work for your life.
