Caring about others is the only thing that IS worth it! I maybe haven't seen what you have, but I have seen enough. I've seen people who don't recognize their families, who think they're someone superheroic and die in the attempt to prove it. I've seen the children of those people, crying because Mommy and Daddy don't recognize them, and they think it's their fault, the children think Mommy and Daddy hate them so much, they invented other people to be. I've seen the ones who can't stand themselves so much they've opened every artery and vein in an attempt to bleed the pain and loathing out. I've seen a lot, but I still manage to care about them, because they need it. Everybody needs at least one person to care. And everybody needs to care about at least one other person. The world just won't go around any other way.
