(((nsomthin)))) I think it's your depression that is preventing you from caring (or feeling like you care) and understanding how people can care about others.

Try and "just" accept that caring is a capacity that many humans have. I believe it's supernatural myself.

As for the media showcasing certain events does make it seem like more people care about that than other non-hyped events. I think people who care, care, and those who don't, don't...regardless of the media events.
