On the bright side, at least you figured this out sooner rather than later. Too often, you find that the average person is someone who goes around thinking everyone else in the world is personally invested in his/her happiness.
But that's never been the case. Self-interest drives our culture, and people are typically disinclined to care about anything outside their own private spheres of interest. This is neither good nor bad; it's simply the way things are.
